EXAMPLE OF THE IQ 710 CALL ORDER PARAMETER
Introduction
The ADTRAN IQ 710 provides disaster recovery protection for Frame Relay circuits. This configuration
guide will describe how the parameter works. The units used in this example are IQ 710s with
C O
ALL RDER
ISDN BRI DBU and T1/DSX cards.
Before You Begin
For this example, each IQ 710 unit will require an ISDN BRI DBU card (P/N 1204004L2) and a T1/DSX
card (P/N 1202803L1).
Network Description
Figure 1 on page 248 is a diagram of the Frame Relay example network used in this configuration guide.
In this example, the host site is Huntsville. Four Permanent Virtual Circuits (PVCs) originate from Hunts-
ville. They are connected to remote sites at Atlanta, Birmingham, Montgomery, and Mobile via DLCIs
200, 400, 600, and 800, respectively. The local DLCIs for the remote sites are 100 for Atlanta, 300 for Bir-
mingham, 500 for Montgomery, and 700 for Mobile. Please remember that DLCIs have local significance
and are assigned by the Telephone Company (TELCO) when the Frame Relay network is built; therefore
the DLCIs for your Frame Relay network will most likely be different from the ones used in this example.
The remaining parameters described in Figure 1 provide a description of the BRI lines that terminate into
the IQ 710s. The Telephone Company will provide you with the Local Directory Numbers (LDNs) and
Service Profile Identifiers (SPIDs) for each of your BRI lines. In addition, you must know which type of
Central Office (CO) switch is providing the ISDN service.
The parameter determines the order in which a list of backup locations will be dialed. If all the
C O
ALL RDER
IQ 710 call order entries are set to none, the IQ 710 will use the first entry with a DBU phone number.
