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.
Higher-Level Protocols
See
ERX Module Guide
,
Appendix A
,
Module Protocol Support
for information about the
higher-level protocols that T3 and E3 interfaces support.
Platform Considerations
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.
COCX-F3 Line Modules and Associated I/O Modules
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:
