3 VoIP B-Series PCBs The 16VOIPU-Bx PCBs are used for converting the RTP (Real Time Transfer Protocol) packets via the IP network and PCM highway. The IP telephones are connected directly to the IP bus. When IP phones need to be connected to a conventional PCM-based digital circuit, this PCB converts the IP packet signal into a PCM signal format and connects to the PCM time division switch. A VOIPU PCB is required in order for IP telephones to communicate with non-voip Aspire phones, as well as to place or receive outside calls. The Bx versions of the Aspire M/L/XL 16VOIPU PCB (P/N ) and 16VOIPDB (P/N ) provide enhanced operation from the Ax versions of the VOIPU PCB and daughter board. (The current Aspire S VoIP PCB (P/N ) and daughter board (P/N ) also provides this enhanced operation).

4 VOIPU-A1 and VOIPU-Bx There are two versions of VOIPU available. The original (and most common) version is the VOIPU-A1. The VOIPU-Bx is now also available. The card version is printed on the edge of the PCB. The table below describes the differences between the two types of VOIPU. Feature VOIP-A1 VOIPU-B1 Supported CODECs G.723, G.729, G.711 G.729, G.711 Minimum VIF Size (This is the Voice Sample Size) G ms G ms G ms G.723 Not supported G ms G ms LTEC Mode (Long Tail Echo Canceller Limitation of DSP Resources A VIF setting of 10ms is not supported. Determined by System Programming If small sample sizes are used, the number of usable DSP resources may be less than the number of ports on the card. Using G.729a or G.723, only 16 channels of a 32VOIPU PCB (16VOIPU with 16VOIPDB) can be used. Card Availability 4VOIPU-A1 (P/N ) 4VOIPDB-A1 (P/N ) 16VOIPU-A1 (P/N ) 16VOIPDB-A1 (P/N ) Program should be set to ON to allow 10ms VIF. Always ON The number of usable DSP resources are equal to the number of ports on the card. (with a 32VOIPU installed under VIF 20ms condition, 32 IP trunks can be used simultaneously) The only limitation is that if 10ms VIF size is selected, only 16 channels of a 32VOIPU (16VOIPU with 16VOIPDB) can be used. 16VOIPU-B2 (P/N ) 16VOIPDB-B1 (P/N ) Conditions When installing a 16VOIPU-Bx PCB with a 16VOIPDB-Bx daughter board, delete the slot s previous PCB information using Program : Slot Control. When installing a 16VOIPU-Bx PCB in a system which has Dterm IP phones, immediately reset the Dterm IP phone to refresh the MAC address in the Dterm IP s memory. If a mixture of VOIPU-A1 and VOIPU-B1 boards are used within a VoIP network, the following should be taken into account: Daughter boards between the Ax and Bx versions of cards are not interchangeable. The VOIPU-A1 does not support 10ms VIF. If this is configured, the system will automatically switch to 20ms VIF and negotiate a CODEC with the party. This is not the case for H.323 trunks - these should be manually set to a minimum of 20ms VIF. With the VOIPU-Bx or VOIPU-S1 (Aspire S system), if (10ms Payload Mode) is set to OFF and the VIF size is set to 10ms, the Aspire changes the VIF size from 10ms to 20ms automatically and negotiates a CODEC with the party. If the system has no choice after negotiation other than to use 10ms (20ms could not be used), then the call will be disconnected. Aspire load shares VOIPU cards. This means that if a VOIPU-A1 and a VOIPU-B1 are installed in the same system, and are configured for 10ms VIF, every second call will fail. To prevent this, use 20ms VIF or above. 2 Aspire VoIP B-Series PCB Installation

With the VOIPU-Bx or VOIPU-S1 (Aspire S system), if (10ms Payload Mode) is set to OFF and the VIF size is set to 10ms, the Aspire changes the VIF size from 10ms to 20ms automatically and negotiates a CODEC with the party. If the system has no choice after negotiation other than to use 10ms (20ms could not be used), then the call will be disconnected. 2. With the VOIPU-A1 and the VIF size is set to 10ms, the Aspire changes the VIF size from 10ms to 20ms automatically and negotiates a CODEC with the party. Limitation For H.323 trunk, Aspire can not change VIF size from 10ms to 20ms automatically. Aspire VoIP B-Series PCB Installation 3

When installing a VoIP PCB, the system allocates the maximum number of trunk ports for the PCB being installed (16 or 32 if a daughter board is installed on the PCB). If the PCB is not going to be used for trunks, the logical trunk ports can be set to 0 in Program : PCB Setup, but the physical trunk ports are still assigned to the PCB and cannot be used for any other PCB. If the trunk ports will not be used and the trunk port usage is a concern, plug the VOIPU PCBs into the system last. The system will allow extension ports to be assigned even if there are no trunk ports available. A maximum of 512 IP extensions or 200 IP trunks are possible with the Aspire. For extension ports the system reserves extension ports in groups of 4; with ports one digital extension port is consumed when the phone is connected. This reduces the maximum number of digital keysets when IP phones exceed 256. If a separate software hub is used (and not the 8SHUBU PCB), it should be a 100Base/full duplex hub. To avoid network problems and to ensure good voice quality, do not use a Repeater Hub/10Base. 6 Aspire VoIP B-Series PCB Installation

VoIP (VOIPDB) Daughter Board The 16VOIPDB-Bx daughter board provides: 16 channels Connector for the 16VOIPU PCB (combination provides a maximum of 32 channels per slot) The VOIPDB-Bx daughter boards are not interchangeable between the VOIPU-Ax PCBs and VOIPU-Bx PCBs. The Ax daughter board must be used on the Ax PCB - the Bx daughter board must be used on the Bx PCB. When installing a VoIP daughter board, the system allocates the maximum number of trunk ports for the PCB (16). If the PCB is not going to be used for trunks, the logical trunk ports can be set to 0 in Program : PCB Setup, but the physical trunk ports are still assigned to the PCB and cannot be used for any other PCB. If the trunk ports will not be used and the trunk port usage is a concern, plug the VOIPU PCBs into the system last. The system will allow extension ports to be assigned even if there are no trunk ports available.

This is also recommended if trunk port availability is an issue as the VOIPU PCB is automatically assigned trunk ports if available. Run a System Information Report (Program 90-13). This report displays all current PCB assignments and port allocations. Some ports you were planning on using may already be assigned. If this is the case, after removing the PCB(s) from the system, delete the slot(s) using Program Install the PCBs, one at a time in the order required, checking for proper (expected) assignments using Program after each PCB is installed.

10 1. If the VOIPDB-B daughter board is to be used: Included with the VOIPDB are four plastic spacers. These are installed in each of the four corners of the daughter board. Make sure to attach the spacers on the front of the daughter board so when installed, the components are facing the VOIPU-B PCB. 2. Position the VOIPDB S CN6 connector over the CN12 connector on the VOIPU PCB. The CN5 connector on the VOIPDB should then be over the CN11 connector on the VOIPU PCB. Press the boards together, ensuring the plastic spacers lock in place. 3. Install the VOIPU PCB into an available slot. When installing a 16VOIPU-Bx PCB with a 16VOIPDB-Bx daughter board, first delete the slot s previous PCB information using Program : Slot Control. Note that the white PCB Pull Tab should always be positioned closest to the top of the cabinet. Figure 2: INSTALLING THE VOIPDB 4. Set the 16VOIPU-B s run/block switch UP. With normal operation, the status LED will flash fast. If trouble was found during the self diagnostics routine, the status LED will flash slowly. 5. Connect the VOIPU-B PCB to the 8SHUBU PCB or to an external switching hub using an ethernet cable. 6. When installing a 16VOIPU-Bx PCB in a system which has Dterm IP phones, immediately reset the Dterm IP phone to refresh the MAC address in the Dterm IP s memory. 7. Refer to Aspire Software Manual (P/N ) for required programming. Upgrading Your VOIPU Firmware 1. Copy the updated firmware file (xxx.bin) to the compact flash card. 2. Remove the VOIPU PCB from the cabinet. 3. Insert the CF (compact flash) card into the VOIPU PCB. 4. Reinstall the VOIPU PCB into the system cabinet while holding the SW1 button down on the VOIPU PCB. 5. Continue holding the SW1 button for approximately 4 seconds. 6. Release the SW1 button. While updating, the status LED1 will be lit steady green. 7. Remove the CF card once the status LED1 starts flashing green. 8 Aspire VoIP B-Series PCB Installation
