7 DA-9B Four-Port Asynchronous Data Module Section Introduction This manual describes the setup and installation procedures for the Intraplex Products DA-9B Four-Port Asynchronous Data Module, Rev. A and above. Experienced users may refer directly to the tables in Section 2 for configuration data. Additional information about this system is contained in your Intraplex multiplexer operation manual. The DA-9B is a four-port data module, designed for use in the Intraplex Terminal and Drop/Insert Multiplexers. The module provides transmission of one to four asynchronous data channels over T, E and other digital communications facilities, with either an RS-232C or an RS-449 data interface. The maximum data rate is 38.4 kbps for one-, two-, or four-channel operation. The module uses one to eight time slots depending on the number of channels used and the data rates of the channels being transmitted. User-adjustable switches allow configuration of several parameters: Maximum data rate Time slot use Transmit/receive direction for drop and insert operation T or E (2 Mbps) system compatibility Starting time slot selection Data loopback for testing Local or remote control access Remote control access address

8 DA-9B Four-Port Asynchronous Data Module Section 2 Functional Description and Setup 2. General Figure 2- shows a simplified block diagram of the DA-9B. The green SRVC LED lights when service is turned on for the module, even if no channel is actually transmitting or receiving data. (SRVC will go off in an E multiplexer if timeslot 6 is selected for use in a CAS formatted signal.) The T switch allows the user to set the module for use in a T or E multiplexer, and the CAS switch, used in an E multiplexer only, determines whether time slot 6 is reserved for CAS signaling. The TERM switch determines whether the module is set up for use in a terminal multiplexer or a drop/insert multiplexer. In a drop/insert multiplexer, it also determines whether the module communicates via the DI-A port or the DI-B port (see Section 2.5, Drop and Insert Operation). RATE and MODE switches set the maximum data rate and whether the module uses one, two, four, or eight time slots. Table 2- shows the relation between the data rate, which data ports are activated, and the number of time slots required. The TIME SLOT SELECT switches determine which time slot(s) are used.

10 DA-9B Four-Port Asynchronous Data Module 2.2 Transmit Side The DA-9B converts asynchronous data to a format appropriate for transmission over T, E (2 Mbps), or other digital circuits made up of 64 kbps time slots. Data interface can be either RS- 232C or RS-449/422, depending on the module adapter installed (see Appendix A). The Intraplex Logic Array contains four transitional coders, one for each port. When a coder detects a change in the state of the data, it generates a three-bit word containing information about that transition. The transmit data is sampled at 256 khz for 38.4 kbps, 28 khz for 9.2 kbps operation, or 64 khz for 9.6 kbps operation. The resulting bitstream passes via the shelf backplane to the common logic module, which multiplexes the data into the aggregate signal for transmission. When used with an RS-232 module adapter, the transmit side of the module has a Clear to Send (CTS) lead for each of the four ports. This signal is always on, and cannot be controlled by RTS. A green DATA IN LED lights when active transmission begins on any active channel and remains lit while transmission continues. 2.3 Receive Side The multiplexer common module demultiplexes the aggregate receive signal and passes the data for the selected time slot to the DA-9B module. When used with an RS-232 module adapter, each port has a Carrier Detect lead which is on during normal operation. While Carrier Detect is on, the module performs transitional decoding, retimes the data, and separates the data channels if more than one data port is active. If the multiplexer loses frame synchronization, all Carrier Detect leads are turned off, and all data ports are set to MARK. Each channel then goes to an RS-232 line driver, which converts it to RS-232 level and passes it to the module adapter. On an RS-232 module adapter, the RS-232C output signal is sent to the output connector. On an RS-449 module adapter, the RS-232 signal is first converted to RS- 449/422 and then sent to the output connector. When the LOOP switch is activated, the receive data coming out of the Intraplex Logic Array is looped back to the transmit input. A green DATA OUT LED lights when on any active channel begins receiving data and remains lit while reception continues. 2.4 Alerts/Alarms The DA-9B sends no Alert or Alarm signals to the shelf common card. 4

11 DA-9B Four-Port Asynchronous Data Module 2.5 Drop and Insert Operation A drop and insert multiplexer operates at a central point on a three (or more) site system. In the example shown in Figure 2-2, Site 2 has a drop and insert multiplexer whose DI-A port is connected to the transmission line to Site, and whose DI-B port is connected to the transmission line to Site 3. Individual payload channels may connect Sites and 2, and 3, or 2 and 3. Note: In the drop and insert multiplexer at Site 2, a DA-9B module can be set to transmit and receive either via the DI-A port (toward Site ) or via the DI-B port (toward Site 3), but not both. When a DA-9B is installed in a terminal multiplexer (Site or Site 3), its TERM switch must be set DOWN. However, when it is installed in a drop and insert multiplexer (Site 2), set the TERM switch DOWN to transmit and receive via the DI-A port (toward Site ) and UP to transmit and receive via the DI-B port (toward Site 3).

However, DA-9 and DA-9E modules can use only one time slot, and can operate in only two modes: one channel with a maximum rate of 9.2 kbps, or two channels with a maximum rate of 9.6 kbps per channel. DA-9A modules have a maximum rate of 9.2 kbps, and can use a minimum rate of 4.8 kbps, which the DA-9B cannot. 5

12 DA-9B Four-Port Asynchronous Data Module To establish a circuit with a DA-9B at one end and a DA-9, DA-9E, or DA-9A at the far end, configure the DA-9B to match the settings of the older module. In a system with two DA-9 or DA-9E modules at the far end, a single DA-9B module may be set to use two time slots and establish circuits with both of them. 2.7 Controls and Indicators The DA-9B has three sets of switches and three LED indicators, as shown on Figures 2-2 and 2-3. The functions of these switches and indicators are described in the following tables.

IMPORTANT: In an E multiplexer set to use CAS signaling, do not use time slot 6 (time slot 6 is reserved for signaling). If the time slot selection would require the use of time slot 6, the card will turn its service off, and it will not operate until the time slot setting is changed. 8

Sets module for local control Sets module for remote control Normal operation - module is active Turns service off 2.6 Remote Control Interface DA-9B modules installed in an Intraplex remote controllable shelf can be used under local or remote control. When under remote control, certain configuration parameters can be changed only via the RS-232 remote port on the multiplexer. See the multiplexer operation manual for details on using ISiCL, the Intraplex Simple Command Language. Before the module can receive remote commands, it must first be assigned a card address. The card address is used to route remote commands and queries to a specific module in a multiplexer. In a full size shelf, it is generally set to the physical slot number the card occupies. It may be set to any number from to 36 which is not in use by another card in the same multiplexer. The card address is determined by the SCB ADDRESS switch bank (S3) settings, as shown in Table

17 DA-9B Four-Port Asynchronous Data Module Table 2-6 Card Address Setting - S3 Card Address Switch Settings:* S3, Positions Card Address Switch Settings:* S3, Positions * 0 = OFF, = ON The DA-9B reports itself as a TYPE 5 card. Its remote operation involves two sets of codes: P (parameter) codes, and S (status) codes, as described in the following two sections P Codes P codes, when used in the parameter field of an ISiCL SET command, allow the user to set parameters on the module via remote control, just like setting the switches on a module under local control. The two P codes for the DA-9B are P and P2. Each is a number from 0 to 255, also represented as an eight-digit binary number (in parentheses). The binary representation is more useful for setting and interpreting the P codes, because each binary digit (0 or ) corresponds to the on or off setting for a particular switch on the module. (Only twelve of these sixteen digits correspond to switches; the other four are not used). Table 2-7 describes the meanings of the P codes.

18 DA-9B Four-Port Asynchronous Data Module P codes also appear in the response to a CONFIG? query, showing the current parameter settings on the card. A typical DA-9B response to a CONFIG? query looks like this: * OK CHANNEL CARD 3, TYPE 5 UNDER REMOTE CONTROL SRVC = ON P0 = 35 (B00000) P02 = 8 (B ); In this sample response, the P codes signify the following: P P2 Module is set to operate with four active ports, maximum data rate 9.6 kbps per port, to use two time slots, starting at time slot #3 Module is set to communicate via the DI-A (TERM) port in a drop/insert multiplexer, the data loopback is off, multiplexer type is E, and CAS is off (time slot 6 not reserved) IMPORTANT: When using binary numbers in the parameter field of a SET command, they must be preceded by the letter B, as for example: <MULTIPLEXER ADDRESS>:<CARD ADDRESS>:SET:P02 = B000000; In addition to the P codes, it is also possible to turn service on or off for the card by sending SRVC = ON or SRVC = OFF in the ISiCL parameter field with a SET command. 2

See Table 2-8 for a list of possible settings. These three digits together configure the data ports (number of active ports, data rate and time slot usage) for the module. See Table 2-9 for a list of possible settings Normal Reserve time slot 6 for CAS signaling (in an E multiplexer only). Sets the module to operate in an E (2 Mbps) multiplexer. Sets the module to operate in a T multiplexer. Normal - loopback off. Loopback active; receive data is looped back to transmit input (all channels). Sets the module to operate via the DI-B port in a drop/insert multiplexer (see Section 2.5). B Sets the module to operate in a terminal multiplexer, or via the DI-A port in a drop/insert multiplexer. 0 Not used. These are the only legal values for setting the parameters. Setting any parameter to a value outside its specified range will produce an unpredictable result. 3

22 DA-9B Four-Port Asynchronous Data Module Section 3 Installation Procedure Refer to the figures and tables in the previous section as necessary during this procedure. Power supply and time slot considerations may affect the installation of this module into an existing multiplexer shelf. Refer to the sections on Channel Module Configuration Guidelines and Adding Channel Modules to Existing Systems in your multiplexer operation manual for more information. INSPECTION: Inspect the module for shipping damage. If you suspect damage to the module, call Intraplex Customer Service. CONFIGURATION:. Choose any unused physical slot in the Intraplex multiplexer for installation of this module. Make sure that the appropriate module adapter is installed at the rear of the slot where you intend to mount this module. Refer to Appendix A in this manual section for information about selecting and installing module adapters. 2. Set the desired port configuration using the RATE, RATE 0, and MODE switches (S, positions - 3), as described in Table Select the desired starting time slot using the TIME SLOT SELECT switches (S, positions 4-8), as described in Table Set for use in a terminal or drop/insert multiplexer using the TERM switch (S2, position 4): UP to communicate via the DI-B port in a drop/insert multiplexer, DOWN in a terminal multiplexer or to communicate via the DI-A port in a drop/insert multiplexer. 5. Select the multiplexer type using the T switch (S2, position 2): UP for E, DOWN for T. 6. If this card is being installed in an E multiplexer, set the CAS switch (S2, position ) to the desired position: UP to leave time slot 6 available for payload, DOWN to reserve time slot 6 for CAS signaling. 7. Verify that the data loopback is turned off: LOOP switch (S2, position 3) UP. 8. Set the address for the card using the SCB ADDRESS switch bank (S3), as described in Table 2-6. This step is not necessary unless you will be using the remote access and control feature, but it is advisable to set each card to a different address during installation to simplify the activation of remote operation in the future. 9. After completing the above procedures, set the module for local control or remote control operation using the following steps. 6

23 DA-9B Four-Port Asynchronous Data Module MOUNTING: A. For local control operation:. Set to local control: REMOTE switch (S2, position 5) UP. 2. Turn service on: OFF switch (S2, position 6) UP. 3. Install the module into the shelf (see MOUNTING, below). B. For remote control operation:. Set to local control: REMOTE switch (S2, position 5) UP. 2. Turn service off: OFF switch (S2, position 6) DOWN. 3. Install the module (see MOUNTING, below). 4. Wait 5 seconds; this loads the parameter settings for the card into the shelf common module. 5. Remove the module and set to remote control: REMOTE switch DOWN. Do not turn service on. 6. Reinstall the module. 7. Verify the configuration via remote control by issuing a CONFIG? query. See Section , Remote Configuration Codes, for an explanation of the CONFIG? response. 8. Set service on via remote control (ISiCL SET command, with SRVC = ON in the parameter field). You can now change the operating parameters for the module using ISiCL commands. For details on using the Intraplex Simple Command Language (ISiCL) for remote access and control, consult your multiplexer operation manual. Insert the module into the selected slot in the Intraplex multiplexer.!!! IMPORTANT: The module must be inserted so that the white ejector tab is at the bottom in a full size (3RU) shelf, or at the right in a compact (RU) shelf. 7

24 DA-9B Four-Port Asynchronous Data Module Section 4 Testing When the DA-9B Data Module has been configured and installed, test it for proper operation before putting it into service. There are two ways you can do the testing: Local testing using multiplexer equipment loopback, with the system out of service. End-to-end testing using far end module data loopback, with the system in service but the channel being tested taken out of service. Use the following procedure to test the modules:. For local testing, activate the multiplexer equipment loopback following the instructions in your multiplexer operation manual. For end-to-end testing, set the loopback (LOOP) switch on the far end DA-9B module ON, and set the multiplexer at one end of the circuit to use loop timing. 2. Connect a data error analyzer (Telecommunication Techniques Corp. Fireberd 2000 or equivalent) to the jack for channel one on the back of the module adapter, using an RJ- cable. 3. Check for synchronization on the output signal. 4. Send single errors on the transmit side and check for single errors on the receive side. 5. Run for 30 seconds and confirm that the signal remains error-free. 6. Repeat test on each channel set up for use in the current configuration. 7. If you used end-to-end testing, return the LOOP switch at far end to OFF position. The system is now operational. If there is an apparent malfunction during end to end testing, first check that the configuration at the two ends is identical. Most problems occur at the common equipment or facility level. Refer to the Troubleshooting section in your multiplexer operation manual for system analysis procedures. 8

27 Appendix A - DA-9B Module Adapters Appendix A Module Adapters - DA-9B The DA-9B Data Module can be installed with one of two optional module adapters, depending on the data interface desired. These are: MA RS-232C, with provision for CTS, TXD, RXD, CD MA-48 - RS-449/422, with provision for SD-A, SD-B, RD-A, RD-B Both of these module adapters provide RJ- connectors for the data ports. Active ports are numbers through n, where n is the number of active data channels. Thus, for single channel operation, use the CH. port; for two channels, use the CH. and CH. 2 ports; and so on. To install either of these Module Adapters: Insert the MA into the rear of the slot that will hold the DA-9B module, secure it with the screws provided, and connect the RJ- lines. The following sections define the pin assignments for these MAs. A-
