Appendix E Mediant 2000 Clock Settings
The gateway can either generate its own timing signals, using an internal clock, or recover them
from one of the E1/T1 trunks.
a
. To use the internal gateway clock source configure the following parameters:
•
TDMBusClockSource = 1
•
ClockMaster = 1 (for all gateway trunks)
b
. To use the recovered clock option configure the following parameters:
•
TDMBusClockSource = 4
•
ClockMaster_x = 0 (for all "slave" gateway trunks connected to PBX#1)
•
ClockMaster_x = 1 (for all "master" gateway trunks connected to PBX#2)
Assuming that the gateway recovers its internal clock from one of the "slave" trunks connected to
PBX#1, and provides clock to PBX#2 on its "master" trunks.
In addition it is necessary to define from which of the "slave" trunks the gateway recovers its
clock:
•
TDMBusPSTNAutoClockEnable = 1 (the gateway automatically selects one of the connected
"slave" trunks)
Or
•
TDMBusLocalReference = # (Trunk index: 0 to 7, default = 0)
Note 1:
To configure the TDM Bus Clock Source parameters, refer to Section

Note 2:
When the Mediant 2000 is used in a ‘non-span’ configuration, the internal
gateway clock must be used (as explained above).
