DESCRIPTION
The E1 Mapper 16-Channel device is designed for add/drop
multiplexer, terminal multiplexer, and dual and single unidi-
rectional ring applications. Four field-proven QE1M Quad E1
Mapper chips are interconnected in a single compact pack-
age to permit higher application board densities.
Sixteen E1 2.048 Mbit/s signals are mapped to and from
asynchronous Tributary Unit-12s (TU-12s) or Virtual Tribu-
tary 2s (VT2s). The E1Mx16 interfaces to a multiple-seg-
ment, byte-parallel SDH/SONET-formatted Telecom Bus at
the 19.44 Mbit/s byte rate for STM-1/STS-3 operation or at
the 6.48 Mbit/s byte rate for STS-1 operation. This Bus per-
mits the E1Mx16 to connect directly to other TranSwitch
devices in application designs. The E1 signals can be either
HDB3 positive/negative rail or NRZ format. The E1Mx16
provides performance counters, alarm detection, and the
ability to generate errors and Alarm Indication Signals (AIS).
E1 facility and line loopback capabilities are also provided.
APPLICATIONS
鈥?STM-1/STS-3/STS-1 to 2.048 Mbit/s add/drop
mux/demux
鈥?Unidirectional or bidirectional ring applications
鈥?STM-1/STS-3/STS-1 termination terminal mode
multiplexer
鈥?STM-1/STS-3/STS-1 test equipment
