Example of the IQ 310 Call Order Parameter
Introduction
The ADTRAN IQ 310 provides disaster recovery protection for Frame Relay circuits. This configuration
guide will describe how the CALL ORDER parameter works. The units used in this example are IQ 310s with
ISDN BRI DBU and T1/DSX modules.
Before You Begin
For this example, each IQ 310 unit will require an ISDN BRI DBU module (P/N 1204004L2) and a
T1/DSX module (P/N 1202803L1).
Network Description
Figure 1 on page 228 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
Huntsville. 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 Birmingham, 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 310s. 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 CALL ORDER parameter determines the order in which a list of backup locations will be dialed. If all the
IQ 310 call order entries are set to none, the IQ 310 will use the first entry with a DBU phone number.
