MITEL SEMICONDUCTOR MT9076AB

Description

The MT9076 is a highly featured single chip solution for terminating T1/E1/J1 trunks. It contains a long haul LIU, an advanced framer, a high performance PLL, and 3 HDLCs.
In T1 mode, the MT9076 supports D4, ESF and SLC-96 formats meeting the latest ecommendations including AT&T PUB43801, TR-62411; ANSI T1.102, T1.403 and T1.408; Telcordia GR-303-CORE.
In E1 mode, the MT9076 supports the latest ITU-T Recommendations including G.703, G.704, G.706, G.732, G.775, G.796, G.823, G.964 (V5.1), G.965 (V5.2) and I.431. It also supports ETSI ETS 300 011, ETS 300 166, ETS 300 233, ETS 300 324 (V5.1) and ETS 300 347 (V5.2).
