Chapter 8. Configuring Dial Backup Options
B-Channel Bit Rate (B-CH BIT RATE)
Select the channel bit rate for the ISDN service. Select 64k unless
your service only provides 56k.
Number of B-Channels (NUM B-CHANNELS)
Select the number of B-channels supported by the ISDN service.
Select 2 if bonding is used.
SPID 1/2
For ISDN dial backup, enter the service profile identifier (SPID)
for both B-channels. The SPID is a sequence of digits identifying
ISDN terminal equipment to the ISDN switch when more than
one ISDN set has been attached to the same central office line.
The SPID is assigned by the telco when the ISDN line is installed
and normally resembles the phone number.
Only the Lucent 5ESS switch is capable of recognizing a point-to-
point configuration, eliminating the need for a SPID. All other
switch types require a SPID.
LDN 1/2
For ISDN dial backup, enter the LDN for both B-channels.
DCE Options
The DCE Options field is available when the ESP External DCE
option card is installed.
Interface Type
Select the connector type for the DCE interface. The choices are
EIA-232 and V.35.
DBU Bit Rate
Set to the operating speed of the DBU interface (0-2048 kbps) to
ensure accurate statistical information.
Phone Numbers 1-5
The IQ Probe stores up to 5 numbers of 36 digits each. Edit a
phone number by reentering the entire number. This process
overwrites the previously stored number.
