Procedure 3 "Installing the MISP" (page 21)).
Installing the clock reference on the SILC
The DSL#0 and DSL#1 on an SILC card can be configured as the reference
clock source, with DSL#0 being assigned for the primary clock reference
and DSL#1 being assigned for the secondary clock reference.
The loop number and location of the primary and secondary clock source is
configured in the Digital Data Block LD 73. Refer to the ISDN Basic Rate
Interface Feature Fundamentals (NN43001-580).
