This register allows selection of the microprocessor access type, and allows
enabling of the per-timeslot configuration registers.
ACCEL:
The ACCEL bit is used to enable an accelerated test mode for production
purposes only. For proper operation the ACCEL bit must be set to logic 0.
MTKC:
The master trunk conditioning bit, MTKC, enables trunk conditioning for all
timeslots, regardless of per-timeslot settings. A logic 1 in the MTKC bit
position enables master trunk conditioning. Data from all of the timeslot Trunk
Conditioning Data registers (40H to 5FH) is output onto the data stream
BRPCM and the per-timeslot signaling trunk conditioning bits A’,B’,C’ and D’
are output onto the signaling data stream BRSIG. The MTKC bit is ORed
with the per-timeslot trunk conditioning enable bits in the Per-Timeslot
Configuration Registers to form the applied per-timeslot trunk conditioning
enables. When the EQUAD is reset, the MTKC bit is set to logic 0, disabling
master trunk conditioning.
The MTKC bit is independent of the TRKEN bit of the EQUAD Receive
Options register and takes precedence over it. If TRKEN is a logic 1, an out-
of-frame condition causes the contents of the ELST Idle Code register to
placed in all time slots on BRPCM. BRSIG presents the frozen signaling. If
MTKC is a logic 1, each BRPCM and BRSIG time slot may have an unique
idle code.
