X11 software release of far-end. This is the current
software release of the far end. If the far end has an
incompatible release of software, it prevents the
sending of application messages, for example, Network
Ring Again.
D-channel clock type for signaling
Source of D-channel clock is external to DCHI card (in
this case the DTI/PRI circuit card). Normally, EXT is
used for PRI/ISL. Note: do not confuse this clock with
the E1 span Clock Controller found on the NTAK10/79.
This clock is in reference to the DCHI synchronous
mode of operation. (Note: If directly connecting two
DCHI ports with out the use of modems, set "CLOK" to
"EXT" on one side and "INT" on the other).
Change LAPD parameters. Enter <cr> if timers are to
be left at default value. The following timers are
prompted only if LAPD is set to YES. The following can
all be left at default during initial set-up.
Interface guard timer checks how long the interface
takes to respond. In units of 0.5 seconds (default 20 =
10 seconds).
Retransmission timer in units of 0.5 seconds (default 3
= 1.5 seconds).
Maximum number of retransmissions
Maximum number of octets in information field
