Appendix - Iv; Procedure For Network Synchronization - C-DOT DSS MAX-XL Installation Manual

Procedure for Network Synchronization

Reference Clock extracted from DTS card in Digital Trunk is to be fed to both copies
of NSC for synchronization purpose. A maximum of 3 reference clock can be
provided at NSC reference clock input. For synchronizing with TAX, reference clock
extracted from DTS card of any digital trunk connected to TAX may be taken as
first reference clock input and selected as first reference clock input. The procedure
for synchronization is detailed below :
* Prepare reference clock cables as per the assembly drawing given. Depending
on no. clocks to be taken as reference, a maximum of 3 cables may be
prepared.
* Two nos. of ICs 26 LS31 are to be mounted on DTS 066/T-S04 card and straps
to be done as per the strap list given. This DTS card is to be used in digital
trunk slot which is used for reference clock. A maximum 3 DTS cards may be
modified depending on no. of reference clocks used (RCLK0, RCLK1, RCLK2).
No changes are required if APC-DTS495/F-S00 card is used.
* Commands used for clock source equippage are given below:
