Reference Guide for the Model RT328 and Model RH348 ISDN Routers

Table B-1 summarizes the different switch types supported by your router and the related information about the switch types (number of phone numbers and SPID numbers). The information in this table refers to a “common” case and is recommended for such a case. However, exceptions still exist to these figures. You can locate the provisioning information for the appropriate North American switch type in the next sections.

Provisioning for Switches in North America

For North America, the Model RT328/RH348 router has been approved by Bellcore and has the IOC (ISDN Ordering Code) “S” Capability, EZ-ISDN1. Ordering your ISDN line in this configuration provides basic data and voice service. If you wish to use any advanced calling

features such as call waiting, you need to order a higher level of service such as IOC“U.” In particular, you need to have ACO (Additional Call Offering) provisioned in order to use call

waiting or incoming call bumping. If your telephone company is not familiar with the IOC ordering codes, ask them what type of switch you will be connected to and whether it is provisioned for National ISDN or a custom protocol. Use the information under each switch to order your ISDN line.

Provisioning for AT&T 5ESS Switch

The AT&T 5ESS switch supports three types of ISDN service: National ISDN-1 (NI-1),

Multipoint, and Point-to-Point.

Table B-2 lists the provisioning features and settings for National ISDN-1 services when using the

AT&T 5ESS switch.
