DS1MX7 Device DS1 Mapper 7-Channel TXC-04201B DATA SHEET FEATURES Seven independent 1.544 Mbit/s DS1 mappers Single byte-parallel Telecom Bus @ 6.48 MHz (28 Slots) or 19.44 MHz (84 Slots) Floating VT1.5 byte-synchronous mapping with signaling only for use with or without a slip buffer Asynchronous mapping for DS1 SONET mapping (VT1.5) or SDH mapping (TU-11 in AU-3 or TU-11 in TUG-3) AMI, B8ZS or NRZ codec for DS1s Serial I/O for control of DS1 line interface transceivers or framers Telecom Bus and DS1 loopbacks with integral PRBS generator and analyzer VT1.5/TU-11 pointer tracking and generation VT1.5/TU-11 overhead processing and insertion one-second latched performance registers and counters DS1 alarm detection and generation Auxiliary port for J2, V5, Z6/N2, Z7/K4 and O-bit access Ring port for USHR/P support Gapped clock option for Internet Applications without need for a framer Intel / Motorola-compatible microprocessor interface 3-bit RDI support Boundary Scan capability (IEEE 1149.1) Single +5 V, ±5 % power supply 208-pin plastic quad flat package Line Transceiver Common Control Interface +5V 4 DESCRIPTION The DS1MX7 is a seven-channel byte-synchronous and asynchronous DS1 mapper. Both SONET and SDH mappings are provided per Bellcore GR-253-CORE (VT1.5) and ITU-T G.707 3-96 (TU-11). A single add/drop Telecom Bus is provided that can operate at either 6.48 or 19.44 MHz, which is compatible with other TranSwitch devices. VT1.5/TU-...
