Introduction
Overview
The ACCULINK
®
316x DSU/CSU acts as an interface between the T1 digital
network and the customer premises equipment, converting signals received from
the DTE (Data Terminal Equipment) to bipolar signals that can be transmitted over
T1 lines. Typical applications include shared access to network-based services,
Local Area Network (LAN)/Wide Area Network (WAN) interconnection, and
fractional T1 network applications.
In addition to the T1 network interface and the DTE Drop/Insert (DSX-1) interface,
the Model 3160 provides two synchronous data ports while the Model 3164
provides four synchronous data ports. The Model 3165 provides one synchronous
data port, but does not provide the DTE Drop/Insert (DSX-1) interface.
The Model 3161 (carrier-mounted DSU/CSU) provides two ports in addition to the
DTE Drop/Insert (DSX-1) interface and is designed to fit into the COMSPHERE
3000 Series Carrier.
