CONTROL REGISTER (CTLR) defines each Output Time Slot OTSy of each Output Time Division Multi-

LOOP: LOOPBACK per channel relevant if two connections has been established (bidirectional or not).
OTSV : OUTPUT TIME SLOT VALIDATED
S1/S0 : Source

: SEQUENCE INTEGRITY
SI = 1, the delay is always: (31 - ITSx) + 32 + OTSy (constant delay).
SI = 0, the delay is minimum to pass through the data memory (variable delay).
LOOP = 1, OTSy, OTDMq is taken into account instead of ITSy, ITDMq.
OTSV = 1, transparent Mode LOOPBACK.
OTSV = 0, not Transparent Mode LOOPBACK.
OTSV = 1, OTSy OTDMq is enabled.
OTSV = 0, OTSy OTDMq is High impedance.

Note:
• Connection
When the source of D channels is selected (GCI channels defined by ITS 1/0) and when the
destination is selected (Output timeslot defined by OTS 0/4; output TDM defined by OM 0/2) the
upstream connection is set up; the downstream connection (reverse direction TDM to GCI) is
set up automatically if ITS 2 bit is at 1. So BID, bit of CMAR must be written at”0”.
• Release
Remember: write S1=1, S0=0 and ITS 2 bit = 0 to release the downstream connection; the up-
stream connection is released when the source changes.
