O RDERING ISDN S ERVICE (US O NLY )
OVERVIEW
This chapter was designed to be a guideline for ordering ISDN service in the United States.
If you are using NI-1 lines, try using EZ-ISDN Codes to order BRI service. If your service provider
does not support EZ-ISDN Codes, try using the NI-1 ISDN Ordering Codes.
If your service providers does not support either types of codes, or, if you are using a non-NI-1 line,
refer to Ordering BRI ISDN Lines using Provisioning Information.
ORDERING NI-1 LINES USING EZ-ISDN CODES
If you are using a NI-1 switch type and your service provider supports EZ-ISDN codes, we
recommend using the EZ-ISDN 1 code. EZ-ISDN 1 provides alternate circuit-switched voice/data
on both B-Channels. There is a CSV/D terminal associated with each of the B-channels.
The B-channels will be given a unique primary directory number capable of making/receiving one
circuit-switched voice or circuit-switched data call. Additionally, calling line Id and additional call
offering (ACO) are also supported. ACO is required to allow incoming voice calls to optionally
preempt or disconnect remote data devices (refer to POTS configuration information and to POTS
configuration elements definitions).
ORDERING NI-1 LINES USING NI-1 ISDN ORDERING CODES
If you are using a NI-1 switch type and your service provider supports ordering codes, use this
section when ordering your ISDN line. We provide recommended NI-1 ISDN ordering codes each
category of CyberSWITCH remote device.
FOR NON-POTS DEVICES
If you have a system without the POTS option, we recommend NI-1 ISDN Capability Package I.
This package includes circuit-switched data on two B channels. Data capabilities include Calling
Line Id. No voice capabilities are provided. The lack of voice feature may save you money.
However, package K or M will also work.
FOR SINGLE POTS DEVICES
If you have a system with a single POTS connection, use Capability Package K plus the ACO option
(additional call offering). Capability Package K includes alternate voice/circuit-switched data on
one B channel, and circuit-switched data on the other B channel. This package provides non-EKTS
voice features, including Flexible Calling, Additional Call Offering, and Calling Line Id. Data
capabilities include Calling Line Id. The ACO option allows an incoming POTS call to disconnect/
preempt a data call if enabled. If you do not wish to use this feature (i.e., you are not using incoming
preemption), dropping ACO may lower your costs.
