Boards in RSP User Frame
RSP board is a remote user processing board, implementing the variable convergence ratio 1:1 to 1:4 to meet different requirements and settings. The convergence ratio is equal to TS on E1s:No. of subscribers. 1:1 240:192 RSPs:8E1s 1:2 120:192 RSPs:4E1s 1:4 60:192 RSPs:2E1s

Boards in RSP User Frame
RSP can be set to two working modes: 1) E1 working mode With E1 working mode, RSP is connected with GV5 unit via E1 interface by using HGRP protocol. One RSP board has up to four E1s to be connected to upper level, thus each RSP unit can provide up to eight E1 ports.

3) The RSP frame works in the local maintenance status when the fourth bit is set as ON and the first, second and third bits are set as OFF; The local maintenance function is used to locate the error and the E1 link is required to form the loop-back at that time. E1 indicator light on the corresponding board will be disabled as well.
