Primary ISDN Modules

For primary WAN connections, ProCurve Networking currently offers two

types of modules:

ISDN BRI U module—used in the United States and Canada

ISDN BRI S/T module—used in all other countries

Both of these ISDN modules support the following standards:

National ISDN-1—Defined in the mid 1990s by the National Institute of

Standards and Technology (NIS) and Bellcore (now called Telcordia),

National ISDN-1 outlines a common set of options that ISDN manufactur-

ers and public carriers must provide.

Northern Telecom Digital Multiplex System (DMS)-100—DMS-100 is

another standard for transmitting voice and data over an ISDN line.

AT&T 5ESS—AT&T switches use Lucent signaling.

In addition, the ISDN BRI S/T module supports:

Euro-ISDN—Also called Normes Européennes de Télécommunication 3

(NET3), Euro-ISDN was defined in the late 1980s by the European Com-

mission so that equipment manufactured in one country could be used

throughout Europe.

Because the two-port ISDN modules have a single TDM clock, you cannot use

one module to connect to two separate service providers. If you lease ISDN

lines from two different service providers, you will need to use two separate

ISDN modules—either 2 two-port ISDN modules or 1 two-port ISDN module

and one ISDN backup module.

Table 8-3 lists the supported ISDN switches, the classifications, and electrical

standards for each ISDN module.
