Introduction
This chapter provides an overview of the T1/E1 WAN port, their characteristics and describes the configura-
tion tasks.
The model 2803 has a T1/E1 WAN port on the rear panel of the unit. The T1 version (Model 2803T) has an
RJ-48C connector, and the E1 version (Model 2803K) offers the user connectivity via either the RJ-48C or
dual coaxial connectors. Both models can be configured for T1 or E1 operation.
The configurable parameters for the T1/E1 port are type (T1 or E1), clock mode (or source) (master or slave),
line code (AMI, HDB3, or B8ZS), framing (CRC-4, ESF, or unframed), line-build-out (for T1 only) and
encapsulation (channelized or HDLC).
A further feature is the creation and configuration of channel-groups.
