•
ERX710 router
• ERX705 router
• ERX310 router
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:
•
See ERX Module Guide, Table 1, Module Combinations for detailed module specifications.
• See ERX Module Guide, Appendix A, Module Protocol Support for information about the
protocols and applications that cOCx/STMx modules support.
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:
•
3 unchannelized/channelized DS3s per OC3
•
84 framed T1s per OC3/STM1
• 63 framed/unframed E1s per OC3/STM1
• 500 fractional T1/E1s per OC3/STM1
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.
Interface Stack
Figure 8 on page 109 shows the stack for cOCx/STMx interfaces.
