Line Module Features; Figure 4: E Series Router Support For Fractional T1/E1 Through - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

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.

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.
