ISDN provisioning information & worksheet
This section describes the process of ordering and provisioning an ISDN BRI line to operate
with the OmniConnect/ISDN. Both the ISDN BRI line configuration and the OmniConnect
configuration are dependent upon the ISDN switch that is used by the local telephone
company that is providing the ISDN service. Some local telephone companies allow the use
of ISDN Ordering Codes (IOCs) to simplify ISDN ordering. The ordering codes reflect a
standard set of commonly used configurations for ISDN BRI. If the local telephone company
does not support IOCs, detailed provisioning requirements must be provided. The following
subsections provide describe provisioning the ISDN line for use with the OmniConnect.

3.5.1.
Data and voice applications over ISDN BRI
The OmniConnect/ISDN supports both data and voice applications. Voice applications can be
initiated via the analog telephone port on the OmniConnect access device. If voice capability
is not required, it is possible in some areas to provision the line for data only support. This
may be the preferred option since some ISDN service providers tariff data only lines less than
data and voice lines.
In addition to supporting both voice and data services, the OmniConnect supports Data Over
Voice (DOV) bearer services. In some service areas, provisioning the ISDN line for DOV
bearer service is more inexpensive than data bearer services. DOV is chosen during the ISDN
configuration process.
The use of the analog line requires the use of Additional Call Offering (ACO) services and a
BRI configured for both voice and data applications. ACO allows the user to receive voice
calls when both B channels are being used for data applications. However, regardless of the
type of ISDN service, a voice call cannot be received when there are data calls that have been
made to two different sites. AT&T Custom services (as opposed to NI-1) have an additional
limitation; a voice call cannot be received when both B channels are being used for data.
Outgoing calls are not affected by this limitation since the OmniConnect controls them.
In North America, if the local ISDN connection is supported by an AT&T 5ESS switch, it is
recommended that IOC U/EZ-ISDN 1, IOC V/EZ-ISDN 1A with support for simultaneous
voice and data or IOC S/S1 (if not using an AT&T switch) is ordered for the OmniConnect. In
order to take complete advantage of the advanced call management features of the
OmniConnect access device, it is required that multiple directory numbers (DN’s) or phone
numbers be ordered along with the ISDN line. OmniConnect accommodates multiple phone
