bandwidth allocated to the port is user-programmable. The data
terminal equipment (DTE) data can occupy contiguous or alternate
channels in the E1 stream, and the channels may start at any
position.
ESU LT Features
• An E1 interface and an Nx56/64 DTE serial interface port.
• Easy configuration capabilities using simplistic menus dis-
played in a liquid crystal display (LCD) window operated by a
front panel keypad.
• Data port supports V.35, EIA-530, V.36, and X.21 electrical in-
terfaces.
• Selectable timing from the network, the Nx56/64 DTE port, or
internally.
• All ones, all zeros, 511, QRSS, and 1:8 test patterns.
• Extensive self-testing and monitoring ensures proper operation.
• Flexible channel allocation (any starting channel and alternate
or contiguous).
• Remote management via 8K inband channel or 64K dedicated
TS0 (using T-Watch as the network manager).
ESU LT CONFIGURATION APPLICATION
The following example illustrates a possible ESU LT application.
Bridge/Router Application
A bridge or router can be interfaced to the network by
using the DTE interface. The bandwidth used is programmable at
Nx56 or Nx64 data rates for E1 or FE1 service. The bandwidth can
