Description
Get status of data interface establishment process at an ISPC SLAVE side
of an ISPC link (where l = loop and ch = channel) which is configured to
convey D-channel signaling.
The status may be:
1. DISABLED = ISPC link is disabled
2. AWAITING ESTABLISHMENT = the data interface establishment
process is waiting to receive DTMF digits. While waiting, dial tone is
provided to the ISPC link at the SLAVE side.
3. RELEASED = the data interface establishment process is stopped
because either an "RLS ISPC" command has been entered or
because the maximum number of tries has been reached.
4. ESTABLISHED = data interfaces at both ends of the ISPC link are
established.
5. AWAITING RELEASE = the ISPC link is being disconnected. Once
disconnected, the link will transition to the "RELEASED" state.
The mode may be:
1. MODE MANUAL N = the data interface establishment process is
running with up to "N" number of tries
2. MODE AUTOMATIC = the Meridian 1 provides dial tone to the ISPC
slave D-channel.
Establish data interface process at the ISPC SLAVE side of an ISPC link at
loop (l) and channel (ch), where "N" = the "number of tries" counter. The
actual range of N = 0-(1)-255.
When N = 0, the mode is set to AUTOMATIC. This mode requires one TDS
slot and one DTR unit. This mode is not recommended for use on small
systems or systems loaded with heavy traffic.
When N > 0, the process is activated for a period of up to N * 30 minutes.
The available range goes from 30 minutes (N = 1) to 128.5 hours or 5 days
(N = 255).
If no value is entered for N, it defaults to a value of 1. When N = 1, one
attempt will be made to establish the data interface process before the
ISPC slave D-channel is released.
Stop the data interface establishment process.
When this command is entered, the mode becomes MANUAL and the
number of attempts to be performed = 0.
