In the above table, ‘1’ stands for OFF status of the switch, and ‘0’ stands for ON status. For example, the
binary code corresponding to 384kbps bandwidth is ‘00110’. Then, the switches shall be set to ‘ON, ON,
OFF, OFF, ON’. When doing this, users are advised to note down the binary code corresponding to the
required bandwidth, then refer to the above table for switch status.
‘Max bandwidth 1’ is the maximum bandwidth in PCM30.
‘Max bandwidth 2’ is the maximum bandwidth in PCM31.

The following conditions shall be satisfied in order to realize the remote bandwidth control function.
1. RCMS2X01-30-FV35 series equipments are deployed point to point, and in pairs.
2. There is no PCM equipment (i.e. DXC, MUX) that takes up the No. 0 timeslot in the link.
3. Neither of the equipment at both sides shall be set to transparent mode (N is not 0).
When all the conditions are met, user can set Master Control at one site and Slave Control at the other
site. The first 5 bits switches can be set to all OFF. After the link is established, the actual bandwidth at
Slave Control site is the same as the Master Control site. Please note that neither of the both sites can
be set to unframed mode (N=0).
This bit switch has nothing to do with the timing resource. Users can either set Master Control at the
Master Clock site, or at the Slave Clock site.
If any of the three conditions cannot be met, then both modems shall be set to Master Control and the
first 5 bits will be used to configure the actual bandwidth. Please note that when N=0, the equipment is
working at unframed mode and this bit switch is invalid.
