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 recommendations
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).
