Table 3-22. ISDN Link Profile Options (1 of 3)

Link Name
Possible Settings: ASCII Text Entry, HQ_Site
Default Setting: HQ_Site for first link; blank for all others
Assigns the name to the ISDN link profile. It is generally the backup destination for a
frame relay link. Each profile must have a unique link name. If the link name field is blank,
the link profile will be deleted. Use ASCII text, 8 characters maximum.
ASCII Text Entry – Assigns a name to identify the ISDN link (maximum 255 characters).
NOTE: To prevent confusion, do not use the following link names: Network, Net1-FR1,
Port-1, or Port-2. These names will be treated as nonunique and the Link Name Not
Unique message appears and you must enter another name.
HQ_Site – The link name configured in the remote site unit (originating a backup call) for
the central site unit (answering a backup call). One link has a default value of HQ_Site to
allow for Automatic Backup Configuration.
Link Status
Possible Settings: Auto, Disable
Default Setting: Auto
Determines whether the ISDN frame relay link is in or out of service.
Auto – The link is configured to be in service when needed. Packets will be transmitted
and received on the interface, and the LMI for a PVC connection will become active when
the link is required. If this profile is configured as the alternate link and the primary link or
DLCI fails, the unit dials the Outbound Phone Number, or the Alternate Outbound Phone
Number if the first call was unsuccessful. The unit also answers calls from Inbound Call
IDs associated with this link. This link profile becomes active when:
This profile is configured as the alternate link and there is a failure of a primary link
or DLCI.
Source or Primary Destination DLCIs are configured on this link.
When the primary link recovers, the call is automatically disconnected.
Disable – The frame relay link is out of service. No data will be transmitted or received on
the interface. If there is are any active calls when disabled, the calls are ended and no
calls will be answered or originated using this profile.
