Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X User Manual

■ See the E120 and E320 Module Guide for modules supported on the Juniper
Networks E120 and E320 Broadband Services Routers.
Interface Specifiers
The configuration task examples in this chapter use the slot/port format to specify
an interface. However, the interface specifier format that you use depends on the
router that you are using.
For ERX7xx models, ERX14xx models, and ERX310 router, use the slot/port format.
For example, the following command specifies an ATM interface on slot 0, port 1 of
an ERX7xx model, ERX14xx model, or ERX310 router.
host1(config)#interface atm 0/1
For E120 and E320 routers, use the slot/adapter/port format, which includes an
identifier for the bay in which the I/O adapter (IOA) resides. In the software, adapter
0 identifies the right IOA bay (E120 router) and the upper IOA bay (E320 router);
adapter 1 identifies the left IOA bay (E120 router) and the lower IOA bay (E320
router). For example, the following command specifies an ATM interface on slot 5,
adapter 0, port 0 of an E320 router.
host1(config)#interface atm 5/0/0
For more information about supported interface types and specifiers on E Series
routers, see Interface Types and Specifiers in JUNOSe Command Reference Guide.
Edge Applications Overview
The E Series router can be used for a number of edge aggregation applications. Two
of the most common are:
■ Private line aggregation
■ xDSL session termination
Private Line Aggregation
A major application of the E Series router is for private line aggregation—the
consolidation of multiple high-speed access lines into one access point. See Figure
1 on page 5.
In this application, the service provider can use a single router to offer high-speed
access (FT1/FE1 through T3/E3) to thousands of subscribers. The individual subscriber
lines can be multiplexed into T3 lines by the service provider and fed into the router.
(The router can also accept unchannelized T3 or E3 connections from high-speed
users and channelized E1 connections directly into the unit.) Once the traffic is
received, the router then handles all IP packet processing, including the assignment
of QoS and routing policies. The packets are then routed into the backbone network.
