Ct3/T3-F0 Line Modules And Ct3/T3 12 I/O Modules; Exchanging Modules - Juniper JUNOSE 11.0.X PHYSICAL LAYER Configuration Manual

JUNOSe 11.0.x Physical Layer Configuration Guide
NOTE: The Juniper Networks E120 and E320 Broadband Services Routers do not
support configuration of channelized T3 interfaces.
For detailed information about the modules that support channelized T3 interfaces
on ERX7xx models, ERX14xx models, and the ERX310 router:

CT3/T3-F0 Line Modules and CT3/T3 12 I/O Modules

ERX7xx models, ERX14xx models, and the ERX310 router support the CT3/T3-F0
line module and CT3/T3 12 I/O module. The CT3/T3-F0 line module and CT3/T3 12
I/O module support both channelized and unchannelized T3 operation. You can
configure a mixture of channelized and unchannelized ports on these modules. For
information about configuring unchannelized T3 ports, see "Configuring Channelized
T3 Interfaces" on page 3.
ERX14xx models support up to 12 CT3/T3-F0 line modules and 12 CT3/T3 12 I/O
modules, ERX7xx models support up to 5 CT3/T3-F0 line modules and 5 CT3/T3 12
I/O modules, and the ERX310 router supports up to two CT3/T3-F0 line modules and
two CT3/T3 12 I/O modules. Each CT3/T3 12 I/O module has 12 physical T3 (DS3)
ports. Each port uses two SMB connectors: one for the transmit (TX) connection and
one for the receive (RX) connection.
CT3/T3-F0 line modules and CT3/T3 12 I/O modules support the following in
channelized mode:

Exchanging Modules

If you replace a CT3/T3 line module and a CT3/T3 I/O module with a CT3/T3-F0 line
module and a CT3/T3 12 I/O module or vice versa, you must erase the configuration
of the existing modules. See the slot accept command in Managing Modules in the
JUNOSe System Basics Configuration Guide.
