•
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, ES2 10G LM, and ES2 10G ADV 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.
Figure 4: E Series Router Support for Fractional T1/E1 Through T3/E3 Interfaces
As shown in Figure 4 on page 11, the router can support fractional, full, and channelized
interfaces.
NOTE: 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.
Line Module Features
The following features are supported by the system line modules:
•
Three different clocking options: internal timing, loop timing, and chassis timing
• DS3 framing type—Both M23 framing and C-bit parity
• DS1 framing type—Both D4 framing mode and ESF framing mode
•
DS3 loopback—For line, payload, diagnostic, and DS1 loopbacks
•
DS1 loopback—For line, payload, and diagnostic loopbacks
