Select the number of B-channels supported by the ISDN service. Select

if bonding is used. This option is not available when a 56k/64k network interface card is installed.
SPID 1
and
SPID 2
-
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.
The
SPID 2
option is not available when a 56k/64k network interface card is installed.
LDN 1
AND
LDN 2 -
Enter the LDNs for both B-channels. The LDNs are assigned by the telco when
the ISDN line is installed. The
LDN 2
option is not available when a 56/64K network interface card is
installed.
