7.7.1. Rules for channel allocation
RC3000-SUB-DV35 is a data user-board with V35 interface and the channel number is
configurable, the rules are as follow:
a. Rules for automatic channel distribution: RC3000 has automatic channel
distribution function. If V35 data is put into the first slot and 1-8 channels of
the first user E1 are idle, system will distribute 1-8 channels of the first user
E1 to it; If V35 data is put into the second slot and 9-16 channels of the
second user E1 are idle, system will distribute 9-16 channels of the first user
E1 to it; If V35 data is put into the third slot and 17-30 channels of the first
user E1 are idle, system will distribute 17-30 channels of the first user E1 to it
(or 17-31 in PCM31 frame mode)
b. Rules for manual channel distribution:
There will be position limitation for manual channel distribution. Here we will
first give the definition of cross connect groups. RC3000 can have 4 E1 at
most and we use 1, 2, 3, and 4 to stand them (each E1 is one cross group,
and now we have cross group 1, 2, 3, and 4), it also has four STBUSes (2M
