1 SRX 210 Services Gateway T1 Interface Configuration To configure a T1 interface: 1. Select Configuration > Quick Configuration > Interfaces if the Interfaces Quick Configuration page is not displayed. 2. Enter information into the Interfaces Quick Configuration page, as described in Table 1 on page Click one of the following buttons: Click OK to apply the configuration and return to the J-Web Quick Configuration page. Click Cancel to cancel your entries and return to the J-Web Quick Configuration page. The properties you can configure on a T1 interface are displayed, as shown in Figure 1 on page 2. SRX 210 Services Gateway T1 Interface Configuration 1

Enter information into the Interfaces Quick Configuration page, as described in Table 1 on page 2. 3.

3 Table 1: T1 Quick Configuration Summary (continued) Add Logical Interfaces Logical Interface Description IPv4 Addresses and Prefixes Defines one or more logical units that you connect to this physical T1 interface. You must define at least one logical unit for a T1 interface. You can define multiple units if the encapsulation type is Frame Relay. (Optional) Describes the logical interface. Specifies one or more IPv4 addresses for the interface. Click Add. Type a text description of the logical interface to more clearly identify it in monitoring displays. 1. Type one or more IPv4 addresses and prefixes. For example: /24 2. Click Add. 3. Click OK. Physical Interface Description MTU (bytes) Clocking (Optional) Adds supplementary information about the physical T1 interface. Specifies the maximum transmission unit size for the T1 interface. Specifies the transmit clock source for the T1 line. Type a text description of the T1 interface to more clearly identify it in monitoring displays. Type a value between 256 and 1504 bytes. The default MTU for T1 interfaces is internal Services gateway's own system clock (the default) external Clock received from the T1 interface Per Unit Scheduler Enables scheduling on logical interfaces. Allows you to configure multiple output queues on a logical interface and associate an output scheduler and shaping rate with the queues. To enable scheduling, select the box. To disable scheduling, clear the box. Encapsulation Encapsulation Specifies the encapsulation type for traffic on the interface. From the list, select the encapsulation for this T1 interface: PPP Frame Relay Cisco HDLC Enable CHAP Enables or disables Challenge Handshake Authentication Protocol (CHAP) authentication on a T1 interface with PPP encapsulation only. To enable CHAP, select the box. To disable CHAP, clear the box. CHAP Local Identity (available if CHAP is enabled) Use System Host Name Specifies that the T1 interface uses the services gateway's system hostname in CHAP challenge and response packets. To enable, select the box (the default). To disable, clear the box. SRX 210 Services Gateway T1 Interface Configuration 3

Specifies one or more IPv4 addresses for the interface. Click Add. Type a text description of the logical interface to more clearly identify it in monitoring displays. 1.

4 Table 1: T1 Quick Configuration Summary (continued) Local Name CHAP Peer Identity CHAP Secret If Use System Host Name is disabled, specifies the local name for CHAP to use. Identifies the client or peer with which the services gateway communicates on this T1 interface. Specifies the secret password for CHAP authentication, known to both sides of the connection. Type a local name for this T1 interface. Type the CHAP client name. Type a password that is known to the other side of the connection. Use a combination of letters and numbers that is difficult for others to guess. T1 Options Bert Algorithm Bert Error Rate Bert Period Byte Encoding Frame Checksum Framing Mode Specifies the bit error rate test (BERT) algorithm to use during a BERT. BERT is supported only when transmission is unframed. (See the Unframed option.) Specifies the exponent n in the bit error rate 10 n. Specifies the length of time in seconds of the BERT. Specifies the byte encoding method. Specifies the number of bits in the frame checksum. A 32-bit checksum provides more reliable packet verification but is not supported by some older equipment. Specifies the framing mode for the T1 line. TBD Type a value between 3 and 7, or 0. For example, a value of 6 specifies that 1 bit out of 1,000,000 is transmitted in error. The default is 0 (no bits are transmitted in error). Type a value between 1 and 240. The default is 10. nx56 7 bits per byte nx64 8 bits per byte (the default) Select 16 or 32. The default value is 16. esf Extended superframe (the default) sf Superframe Invert Data Enables or disables data inversion. Data inversion is normally used only in alternate mark inversion (AMI) mode. To enable, select the box. To disable, clear the box. 4 SRX 210 Services Gateway T1 Interface Configuration

Type a local name for this T1 interface. Type the CHAP client name. Type a password that is known to the other side of the connection.

5 Table 1: T1 Quick Configuration Summary (continued) Line Buildout Line Encoding Loopback Timeslots Specifies the T1 line buildout in feet for cables 655 feet (200 m) or shorter, or in decibels for longer cables. Line buildout compensates for the loss in decibels based on the distance from the device to the first repeater in the circuit. Specifies the line encoding method. Configures the T1 interface as a loopback interface for testing purposes. When T1 is configured as a local loopback interface, the device transmits test traffic simultaneously to the CSU and to the receiver at the T1 interface. When T1 is configured as a remote loopback interface, test traffic transmitted by the CSU is simultaneously received at the T1 interface and transmitted back to the CSU. Specifies the number of time slots allocated to a fractional T1 interface. By default, a T1 interface uses all the time slots. From the list, select one of the following line buildouts: (0 40 m) (the default) (40 81 m) ( m) ( m) ( m) long-0db long-7.5db long-15db long-22.5db ami Alternate mark inversion b8zs Binary 8 zero substitution (the default) From the Loopback list, select one of the following: local Traffic loops from the transmitter to the receiver at the T1 interface during tests. remote Traffic loops from the receiver to the transmitter at the T1 interface during tests. Type numeric values from 1 through 24. You can use any combination of time slots. To configure ranges, use hyphens. To configure discontinuous slots, use commas. For example: 1 5,10,24 CLI set interface t1-1/0/0 unit 0 family inet address <ipaddress/mask> set security zones security-zone zone1 interfaces t1-1/0/0.0 host-inbound-traffic system-services all set security zones security-zone zone1 interfaces t1-1/0/0.0 host-inbound-traffic protocols all set security policies default-policy permit-all Related Topics Configuring the SRX 210 Services Gateway Mini-Physical Interface Modules SRX 210 Services Gateway E1 Interface Configuration SRX 210 Services Gateway T1 Interface Configuration 5
