1. 1 About the DC3X00
The DC3X00 is used to interface between a fractional E1 (2
.
048Mbit/s) Nx64K service and
an X.21 or V.35 port which connects to a bridge or router. The model DC3000 has an X.21
interface, and the model DC3200 has a V.35 interface. Both models are described in this
manual. There is a choice of either BNC or RJ45 connectors for the E1 service on the rear
panel of the unit. DC3X00’s are used in pairs, one on either side of a WAN (Wide Area
Network) link.
