NEAX2400 ICS ISDN PRI Installation Notes
ETI-152A Page 2
1. GENERAL DESCRIPTION
This ETI describes the installation procedures and office data assignment for connecting ISDN
lines to NEAX2400 ICS. The ISDN PRI (Primary Rate Interface 23B + D) allows a station user to
gain access to a variety of services, associated with the ISDN, based on the office data assigned.
This ETI, which is not intended as a general ISDN training document, assumes the craft person is
fully trained in the programming and installation of the NEAX2400 and has the necessary ISDN
knowledge.
2. ISDN OVERVIEW
2.1 Layer 1 Physical Interface
ISDN PRI is a T1 interface which should be configured to ESF B8ZS rather than to D4
AMI. Configuration to ESF B8ZS will avoid falls framing and yellow alarm emulation
problems that can occur when digital data is transported with a D4 format. If ESF with B8ZS
is unavailable, the D channel speed should be set for 56Kbpps instead of 64Kbpps. This
speed setting also applies to data transmitted over the B channels. See Table 2 for 24PRT
Switch Settings.
ISDN PRI uses out-of-band message oriented signaling, carried in a separate digital (or “D”)
channel. The D channel in any PRI interface must be in time slots 24 of the DS1. The
remainder of the 23 bearer (or “B”) channels carry voice or data.
When multiple DS1s for ISDN PRI are provided to a given customer location, two methods
of using D channels are used. The first method uses a D channel for each interface. The
second method uses one D channel for several interfaces; this is called Non-Facility
Associated Signaling (NFAS). A D channel backup may be provided in the case of NFAS.
This channel is in stand-by mode and will take over in case of primary D channel failure.
Please note that there are two assignments in ATRK for any ISDN D channel. One
assignment represents the Physical channel on the 24PRT; the second assignment represents
the D channel handler (DCH) part of the 24PRT.
2.2 ISDN PRI Protocol
ISDN protocol depends on the switch type used by the central office. You should have this
information prior to installation since switch settings and data assignment are different for
each protocol.
The NEAX2400 supports AT&T 4ESS and 5ESS protocol, as well as NT DMS100/
DMS250. Currently, the NEAX2400 does not support the National ISDN protocol for PRI.
Arrangements should be made with the central office to configure the protocol for custom
and not for National ISDN PRI. The National ISDN PRI is mostly used in AT&T 5ESS and
NT DMS100/250. AT&T 4ESS only supports AT&T protocol at this time.
ISDN PRI protocol can be broken into two types of protocol. The first type, User to Network
Protocol, allows connection of a PBX to a network. The second type, Symmetrical Protocol,
allows PBX to PBX connection via private lines.

Page 3 ETI-152A
NEAX2400 ICS ISDN PRI Installation Notes
The PBX supports User to Network protocol; however, provision has been made for the
PBX to be configured as a network for test purposes. In applications where two PBXs are
connected via private lines, one PBX may be configured as a network (however, NEC does
not guaranty this type of operation).
2.3 ISDN PRI Services
ISDN PRI offers a number of features and services. It is important to know the type of
services the customer has ordered with the ISDN PRI at the time of installation. This
information will help you to configure the PBX correctly.
The services may be provided by the carrier through Servicing Provisioning (or Fix) or as
Call-by-Call (CBC) Service Selection. Servicing Provisioning is a type of service dedicated
to specific ISDN interfaces or channels. CBC is a service where channels are not dedicated
to a specific service and are, therefore, not channel dependent.
CBC is also distinguished by its use of the Network Specific Facility (NSF). The NSF uses
various information elements in the setup message for each given call and allows for the
identification of the type of service requested when a call is placed. In the case of CBC, the
NSF needs to be sent by the PBX to the network with each call. The ACBC command is
used for setting CBC. This command also allows you to program the type of numbering plan
(examples include national, international, or private; type of network (AT&T or NT); and
type of service or feature). When the NSF is not sent when requested or is not recognized by
the network, the call will be rejected. The customer should provide information regarding
the types of subscribed services. In the case of Local CO where the services subscribed to
are DOD and DID on a same ISDN interface without the NSF, the programming of the NSF
is unnecessary.
The ACBC command is also used to indicate to the network the long distance carrier
selection code. An example of this would be when the ISDN is provided by the local carrier
and long distance is provided by AT&T, MCI, or Sprint. This is called Transmit Network
Selection (TNS).
The number provided by the user to the network or PBX is the Calling Party Number (CPN).
The CPN is programmed with ACNP and ACND commands. These commands add the area
code number and office code numbers to the extension number from where the call
originated. If multiple CPNs are required, the AANDE command should be used; this
command will allow the assignment of one CPN per individual tenant. The AANDE
command will override the ACNP and ACND commands. The CPN can be privacy optioned
with the feature class of service using the ASFC SFI 94. The privacy option service notifies
the network and called party to restrict the presentation of the CPN. If SFI 94 was set to 1,
the network will deliver the CPN to the called user with “Presentation Restricted” in the
indicator field. It is the responsibility of the user to restrict the CPN when the CPN and the
“Presentation Restricted” message are received at the same time.
The ISDN network can deliver two types of caller ID - Billing Number (BN) or Calling
Party Number (CPN). Two additional SFIs - 97 and 98 - are used to indicate which caller ID
is preferred to be received from the network.

Note 1: Each ISDN interface requires assignment of 23 B channels and 2 D channels.
Note 2: There are two assignments in ATRK for any ISDN D channel. One assignment
represents the Physical channel on the 24PRT; the second assignment represents
the D channel handler (DCH) part of the 24PRT.
