Channel IE Type Choose one of the following values to specify whether channel
selection is presented as a channel map or a slot map:
• Timeslot Number—B-channel usage always indicates actual
timeslot map format (such as 1-15 and 17-31 for E1).
• Slotmap—B-channel usage always indicates a slot map format.
• Use Number When 1B—Channel usage indicates a channel
map for one B-channel but indicates a slot map if more than one
B-channel exists.
• Continuous Number—Configures a continuous range of slot
numbers (1-30) as the E1 logical channel number instead of the
noncontinuous actual timeslot number (1-15 and 17-31).
PCM Type Specify the digital encoding format. Choose one of the following
formats:
• a-law: Use for Europe and other countries, except North
America, Hong Kong, Taiwan, and Japan.
• mu-law: Use for North America, Hong Kong, Taiwan, and
Japan.
Delay for first restart (1/8 sec
ticks)
Enter the rate at which the spans are brought in service. The delay
occurs when many PRI spans are enabled on a system and the
Inhibit Restarts at PRI Initialization check box is unchecked. For
example, set the first five cards to 0 and set the next five cards to 16.
(Wait 2 seconds before bringing them in service.)
Delay between restarts (1/8 sec
ticks)
Enter the time between restarts. The delay occurs when a PRI
RESTART gets sent if the Inhibit Restarts check box is unchecked.
Inhibit restarts at PRI
initialization
A RESTART or SERVICE message confirms the status of the ports
on a PRI span. If RESTART or SERVICE messages are not sent,
Cisco Unified Communications Manager assumes the ports are in
service.
When the D-Channel successfully connects with another PRI
D-Channel, it sends a RESTART or SERVICE message when this
check box is unchecked.
Enable status poll Check the check box to enable the Cisco Unified Communications
Manager advanced service parameter, Change B-Channel
Maintenance Status. This service parameter allows you to take
individual B-channels out of service for an MGCP T1/E1 PRI
gateway in real time.
Uncheck this check box to disable the service parameter, Change
B-Channel Maintenance Status.
Note Default leaves this field unchecked.
Unattended Port Check this check box to indicate an unattended port on this device.
