Configuring the 12-Port Channelized T1/E1 Circuit Emulation PIC Operating Mode
This section contains the following topics:
T1/E1 Mode Selection
After the PIC is brought online, 12 ct1 interfaces or 12 ce1 interfaces are created, depending on the T1 or E1 mode selection of the PIC.
Figure 1 and Figure 2 illustrate the possible interfaces that can be created on the 12-port T1/E1 Circuit Emulation PIC.

12-Port Channelized T1/E1 Circuit Emulation PIC Configuration Statements
Setting the T1/E1 Mode at the PIC Level
To set the T1/E1 mode at the PIC level, enter the following command:
Or specify the following:
After the PIC is brought online, 12 ct1 interfaces or 12 ce1 interfaces are created.
If the mode is not manually configured, then the PIC defaults to T1.
Creating an ATM Interface on a CT1 or CE1
To create an ATM interface on a CT1, enter the following command:
Or specify the following:
To create an ATM interface on a CE1, enter the following command:
Or specify the following:
The interface at-fpc/pic/port is created.
You can use the show chassis hardware command to display a list of the installed PICs.
