Configuring Support of 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module

The 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module has 12XDS1, 4XDS3, electrical interfaces, and 4XSFP ports that can provide multiple functions such as 1XOC-48/12/3 and 3XOC-12/3. The maximum speed supported on OCx ports is OC-48. The interface module supports a maximum of 3G CEM traffic.


Note

In addition to support on RSP2 module, the IM is supported on RSP3 from the Cisco IOS XE 16.9.x release.

Restrictions of Feature Support on 4 Port OC48/OC12/OC3 + 12 Port T1/E1 + 4 Port T3/E3 CEM Interface Module

  • Mixed mode support, for example, DS1 and E1 or DS3 and E3 or SONET and SDH simultaneously on different ports is not available.

  • E1/E3, Unidirectional Path Switching Ring (UPSR), and Data Communication Channel (DCC) are not supported.

  • Multiservice functionality: MLPPP, FR, and MLFR are not supported.

  • EoS and EoPDH are not supported.

  • The configure replace command is not supported.

  • A combination of T1/T3/SONET with E1/E3/SDH modes are not supported.

  • When IM is used with RSP3 module, then it is not allowed in slots 0 and 1 on NCS42xx chassis.

  • Synchronization Status Message (SSM) is not supported on T3 ports.

Enabling T1 Controller


Note

T1/T3 or E1/E3 does not require any license.

To enable T1 controller:

enable
configure terminal
controller mediatype 0/4/0
mode t1
end

Configuring the Controller

To configure T1 interface, use the following commands:

enable
configure terminal
controller mediatype 0/4/0
mode t1
exit
controller t1 0/4/0
clock source internal
framing esf
cablelength short 110
linecode b8zs
no shutdown
exit
