ISDN and T1 Clocking
When combining BRIB, PRIB, and T1 cards in one KSU, specific settings
and cabl ing ar e imp ort ant for p rope r clocki ng. The Phas e Lock Loop Uni t
(PLLU) synchronizes the clock ing from the Central Office to the clock ing
oftheKSU.Popping,crackling,droppedcalls,andone-waytransmission
ar e u sual ly at tr i but ed to the c l oc king not be ing sync h roni ze d cor r ec t ly.
Exa mples - Set ting s an d C abling
The following exa mples cla rify the clocking and cabling for thes e ca rds :
(1) T1IB and (1)PRIB
If both cards in a phone switch are connected to a telephone compa ny
clock (not point- to -point T1), put the T1 clock switch in th e enab le
position (UP) to allow it to receiv e clocking from the teleph one com pany
dire ctly, a nd do not install the clock cab le . Se t the PRIB clock switch in the
disable position (OFF), which allows the PRIB to synchronize its timing off
of the backplane (fro m the T1 clo cking). If the T1 is a point-to-point T1,
se t the P R I B in th e e nab le pos it ion (ON ), t he T1 i n t he di sab le pos it ion
(OF F), and do not install th e clock ca ble .
Whe n the swi tch is in the“up”position, it shouldbe considered“ON”.When
the swi tch is in t he“down”pos iti on, it s ho uld b e con si der ed“OF F”.
Th e cab le con nec tion foll ows th e sa me log ic -“up”is c lock o uts ide (O N) a nd
“do wn”is clo ck ins id e (O F F). O N mea ns tha t clo cki ng is comi ng fr om ou tsi de

If both cards in a phone switch are connected to a telephone compa ny

position ( ON) to a llow it to receiv e clockin g from the telephone company
directly. Do not install the clock cable.
Se t the BRIB clo ck switch in the d is able position ( OFF ), which allows th e
BRIB to s ynchronize its timing off of the ba ck pla ne (from the T1 clock ing).
If the T1 is a point-to-point T1, set the BRIB to the enable position (ON),

The clock cable should be connected to the OUT position on the
connector on the PRIB1. The clock cable should b e conn ected to the IN
position on PRIB2. SW2 of the PRIB1 and PRIB2 shou ld be placed in the
ON position. The three T1IBs are not connected with the clock control

The clock cable should be connected to the OUT position on the cable
connector on the T1IB and conne cte d to th e IN pos ition on the conne ctor
on the T1IB2. The clock cable should be connected to th e OUT pos ition
on T 1IB2 and connected to the IN position on the T1IB3. SW3 of T1IB1
should be placed in the ON position, with SW3 on T1IB2 and T1IB3 being

3. Locate the CONN3, a nd CONN4 conne ctors on the SLIB ( outline d).
4. Position the MSG12 module so that the CONN3 and CONN4
connectors match up with th e CONN3 an d CONN4 connectors on the
SLIB respectively.

Exampl e: If the modem can achieve 28800 on a direct CO line, the
maximum speed on an SLT po rt would be 26400.
Testing proves that a baud rate o f 33600 can be achieved with SLT-T1
lines. Typical connection speeds with SLT-T1 are 22700-33600. Typical
connection speeds with SLT-Loop/Grou nd Start are 17400-23800.
