Use the seizure-ack enable command to configure the originating point to 
require the terminating point to send seizure acknowledgement signal during R2 
line signaling exchange.

Use the undo seizure-ack enable command to restore the default.

By default, the originating point requires the terminating point to send seizure 
acknowledgement signal.

This command applies to R2 signaling only.

Normally, the terminating point acknowledges received seizure signals. The R2 line 
signaling coding schemes in some countries however do not require the 
terminating point to do this. To accommodate to these schemes, you can 
configure the undo seizure-ack enable command, allowing the terminating 
point not to acknowledge received seizure signals.

max: Selects the timeslot with the greatest number from currently available 
timeslots.

maxpoll: Selects the timeslot with the greatest number from available timeslots in 
the first timeslot polling; in later pollings, selects in descending order timeslots 
with numbers less than the one picked out in the previous polling. Suppose TS31 
and TS29 are not available. In the first polling, TS30 will be picked out for use and 
in the next polling, TS28.

min: Selects the timeslot with the lowest number from available timeslots.
