that the service provider needs to give you, and which you need to give to the service provider.

ISDN Line Ordering and Configuration

Arranging ISDN Service

The service provider requires certain information about the capabilities of the CyberSWITCH 100.
You must give the service provider the required switch settings (parameters) for the provider’s
central office switch. Consult with your service provider at least two months before you require the
installation and use of the ISDN service.

Complete the following steps to arrange your ISDN service:

1.

Contact the service provider and determine what type of ISDN central office switches are
available (see

2.

Supply the service provider with the provisioning information for their switch type to enable
proper configuration of the ISDN line (see

3.

Once the ISDN line is installed, ensure that the service provider supplies you with the following
information:

•

ISDN telephone numbers

•

ISDN Service Profile Identifier numbers (SPIDs) and/or Directory Numbers (DNs) (see

CyberSWITCH 100 Advanced User Information 1

ISDN Line Ordering and Configuration

Telephone Switch Support

Your telephone company may offer a v ariety of ISDN switch types. You must contact your service
provider and find out which type of ISDN service is available.

The following switch types are currently supported by the CyberSWITCH 100 within the U.S.:

• National ISDN 1 (NI-1)

• AT&T 5ESS w/Custom Software

ISDN BRI Line Configuration

You need to order one Basic Rate Interface (BRI) ISDN line from your service provider . The Basic
Rate Interface ISDN line provides two full duplex 64 (Kbps) B channels used for voice, data, fax,
etc. and one full duplex 16 Kbps channel used for signaling. Each B channel can be used for a call;
i.e., two calls can occur at the same time. Services vary from individual service providers.

Full 64 Kbps for each channel (referred to as “clear channel”) may not be available

NOTE

The service provider requires some information from you about your configuration. You must
provide your service provider with the required switch settings for the provider’s telephone switch

signaling (the 8 Kbps signaling is taken from the B channel bandwidth) so that you
may only achieve a 56 Kbps channel speed.

in this chapter). Consult with your service provider at least

ISDN Line Ordering and Configuration

In the U.S. and Canada, an NT1 Network Terminator is required to provide an interface between
the CyberSWITCH 100 and the ISDN line. The NT1 offers conversion between the two-wire
twisted pair (U-loop interface) used by telephone companies and the four-wire terminal equipment
(S/T Interface) as well as line-testing capabilities. You can order the CyberSWITCH 100 with an
internal NT1 (

CSX103

or

CSX105

) or use your own NT1 equipment

(CSX101, and CSX104

).

External Network Terminator equipment comes with its own power supply (built-in or external).
In Europe and Japan, the telephone company provides the NT1 and offers end-users the S/T

interface. The S refers to a connection between customer equipment in some ISDN configurations
when a PBX is present. The T refers to the connection between the NT1 device and the
CyberSWITCH 100.

The ISDN pairs are the same wires that exist for analog telephone service. In most cases, the same
wires can be used for the ISDN line. The EIA/TIA standard for wiring is Unshielded Twisted Pair
(UTP) cable. Category 3 or above, 24 AWG (American Wire Gauge). The standard also
recommends using 8-contact RJ45 jacks for new ISDN service installation. No special
conditioning is required; in some cases, conditioning must be removed.

ISDN BRI Configurations

ISDN BRI lines can be configured in point-to-point and multi-point configurations. With a
point-to-point configuration, only one device is connected to the ISDN line. With a multi-point
configuration, it is possible to have up to 8 devices (telephones, faxes, routers, etc.) connected to
the line.

Since the ISDN BRI line is used for a high speed LAN-to-LAN link, you must ensure that
additional devices connected to the S/T interface allow sufficient access for the bandwidth
requirements of the CyberSWITCH 100. The device support through the POTS (Plain Old
Telephone Service) interface allows multiple devices per port, but only one call initiated at a time
(though another call can be in progress).

CyberSWITCH 100 Advanced User Information 3

ISDN Line Ordering and Configuration

SPIDs, Directory Numbers and Telephone Numbers

The service provider gives you up to three sets of numbers for identifying the ISDN line and
devices. You may be assigned none, one, or two Service Profile Identifier numbers (SPIDs) or
Directory Numbers (DNs) depending on the service provider and country.

Directory Numbers

A Directory Number (DN) is the phone number of your ISDN line, assigned by your telephone
company. Some digital central office switches (AT&T 5ESS Custom) require only a single DN
Number for your CSX100. Others, like the AT&T 5ESS with the NT1 service, or the Northern
Telecom DMS-100 with the NT1 service, require a separate number for each B channel.

Service Profile Identifiers

SPIDs, also assigned by the ISDN service provider, identify the services and features that the
telephone company switch provides for your ISDN line. Commonly implemented in the U.S. and
Canada, the SPID is often derived from the directory number, combined in a series with other
digits. SPIDs are not generally implemented outside the U.S. and Canada.

Once you have contacted your service provider and learned the type of ISDN switch being used,
refer to Tables 1 through 3. You must supply the appropriate provisioning information to the
service provider to ensure proper configuration of the ISDN line.
