Higher-Level Protocols

For message strings that are unique to a particular message type, the line module must

receive another message of the same type containing this string in order to retain the

local copy of the string and reset the timer. For example, if the line module receives a

test signal message containing a generator string and does not receive another test signal

message within 10 seconds, it will erase the local copy of the generator string.

See ERX Module Guide, Appendix A, Module Protocol Support for information about the

higher-level protocols that T3 and E3 interfaces support.

You can configure unchannelized T3 and unchannelized E3 interfaces on the following

E Series Broadband Services Routers:

ERX1440 router

ERX1410 router

ERX710 router

ERX705 router

ERX310 router

NOTE: The E120 and E320 Broadband Services Routers do not support configuration

of unchannelized T3/E3 interfaces.

For detailed information about the modules that support unchannelized T3/E3 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 unchannelized T3/E3 modules support.

ERX7xx models, ERX14xx models, and the ERX310 router support the COCX-F3 line

modules and associated I/O modules.

ERX14xx models support up to twelve COCX-F3 line modules and twelve corresponding

I/O modules, ERX7xx models support up to five of these line modules and five

corresponding I/O modules, and the ERX310 router supports up to two of these line

modules and two corresponding I/O modules. There are twelve physical T3/E3 (DS3)

ports per I/O module. Each port uses two SMB connectors: one for the transmit (TX)

connection and one for the receive (RX) connection.

COCX-F3 line modules and associated I/O modules support the following:
