Platform Considerations
You can configure cOCx/STMx interfaces on the following E Series Broadband Services
Routers:
NOTE: The E320 router does not support configuration of channelized OCx/STMx
interfaces.
For detailed information about the modules that support cOCx/STMx interfaces on
ERX7xx models, ERX14xx models, and the ERX310 router:
cOCx/STMx FO Line Module
The cOCx/STMx F0 line module pairs with either a cOC3/STM1 I/O module or a
cOC12/STM4 I/O module to support channelized T3 (DS3), T1, E1, FT1, and FE1
signaling. Each connection is made through standard SC connectors.
The cOCx/STMx line module supports the following:
You can combine the cOCx/STMx line module with four-port cOC3/STM1 I/O modules
or one-port cOC12/STM4 I/O modules. cOC3/STM1 I/O modules support one
OC3/STM1 per port. cOC12/STM4 I/O modules support all four OC3/STM1s on one
port.
The cOCx/STMx line module and its corresponding I/O modules can support either
E1 or T1 operation. These modules cannot support E1 and T1 operation
simultaneously.
