PRI to Echo canceller pin assignments

The echo canceller is controlled by an RS-232 port on the PRI circuit pack. The following tables give the echo canceller pin assignments, operating parameters and initialization procedures.

See Table 70 "PRI-to-Echo canceller - pin assignments" (page 192) for PRI-to-Echo canceller pin assignments; refer to Figure 75 "PRI to echo canceller cabling" (page 193) for a PRI-to-Echo-canceller cabling schematic.

Electromagnetic Interference

The Electromagnetic Interference (EMI) ﬁlter assembly for PRI is PO643763. The system meets FCC Part 15, Subpart J, Class A requirements regarding EMI. In order to accomplish this, the SDI cables must exit the cabinet through EMI ﬁlters on the I/O panel. This procedure depends on the system cabinet type.
