Configuring Physical Layer Interfaces
The router supports a number of line rates; some
of these are listed per line module below.
- COCX-F3 line module supports unchannelized E3.
- Channelized OCx/STMx (cOCx/STMx) line module supports
DS3 channelized to DS1, fractional DS1, or the DS0 level; unchannelized
DS3; E1/T1 channelized to fractional DS1; unframed E1.
- CT3 12-F0 line modules support DS3 channelized to DS1,
fractional DS1, or the DS0 level. CT3 12-F0 line modules also support
unchannelized T3.
- IPSec Service module provides tunnel service for secure
tunnels.
- GE/FE line module supports Gigabit Ethernet and Fast Ethernet.
- GE-2 line module and GE-HDE line module support Gigabit
Ethernet.
- OCx/STMx ATM line module supports OC3/STM1 ATM, OC12/STM4
ATM, and unchannelized T3.
- OCx/STMx POS line module supports OC3/STM1 POS and OC12/STM4
POS.
- OC48 line module supports OC48/STM16 POS.
- OC3/STM1 GE/FE line module supports OC3/STM1 ATM and Gigabit
Ethernet.
- ES2 4G line module (LM) supports OC48/STM16 POS, OC12/STM1
POS, OC3/STM1 ATM, OC12/STM1 ATM, Gigabit Ethernet, 10-Gigabit Ethernet,
and tunnel-service interfaces.
- ES2 10G Uplink LM and ES2 10G LM supports 10-Gigabit Ethernet
interfaces.
- COCX-F3 line module supports unchannelized T3.
- Service Module (SM) provides tunnel service for IP tunnels
and LNS termination.
A variety of protocols are supported over these
interfaces, including IP/Frame Relay, IP/ATM, IP/PPP, as well as the
protocols to enable B-RAS services. The router’s DSx and E1/E3
implementations support termination, statistics gathering, alarm surveillance,
and performance monitoring. These links can be used for either network
ingress or network egress.

T1/E1 Through T3/E3 Interfaces
As shown in Figure 4, the
router can support fractional, full, and channelized interfaces.

See ERX Hardware Guide, Chapter 4, Installing
Modules and E120 and E320 Hardware Guide, Chapter 4, Installing Modules, for
a discussion of slot groups and modules. See the ERX Module Guide
and the E120 and E320 Module Guide, for a discussion
of the combination of line modules allowed in E-series routers.
