Use the INTERFACES menu to view and configure parameters for the T1, ETHERNET, V.35, FXS, FXO,

DSX-1 MODULE, and UBR1TE interfaces as shown in Figure 6.

Figure 6. Interfaces Menus

INTERFACES (NETWORK T1)

View the network T1 interface status and configure T1 parameters from this menu.

INTERFACES (T1) > CONFIG

Configure the various T1 parameters and enable/disable loopbacks from this menu.

INTERFACES (T1) > CONFIG > TIMING MODE

Choices are NETWORK and INTERNAL. Select NETWORK when the unit will receive timing from the network.

Select

INTERNAL when the unit will generate the timing. Default is NETWORK.

INTERFACES (T1) > CONFIG > FORMAT

This sets the frame format for the T1 interface. The setting must match the frame format of the circuit to

which the interface is connected. Choices are

ESF or SF (D4). Extended Superframe (ESF) provides a

non-disruptive means of full-time monitoring on the facility datalink (FDL). Default is

ESF.

INTERFACES (T1) > CONFIG > LINE CODE

This sets the line code for the T1 interface. The setting must match the line code of the circuit to which the

interface is connected. Choices are

B8ZS (bipolar with 8-zero substitution) and AMI (alternate mark

inversion). Default is

B8ZS.
