Nortel Communication Server 1000S Installation And Configuration Manual page 93

Note: Packet data testing can be conducted only if an external packet
handler or an Meridian Packet Handler (MPH) is installed as part of the
customer configuration, and is supported by the system (like the external
DPN-100 packet handler). If packet handler is not part of the
configuration, do not equip the DSLs with packet data terminals and skip
all the packet data tests specified in this chapter.
3 Equip the UILC DSL with a network terminator (NT1) and connect the two
voice and one circuit-switched data ISDN BRI terminal to the S/T interface
on the NT1.
4 Configure the DSLs to support these ISDN BRI terminals and initialize the
terminals as described in the "Initialize ISDN BRI terminals" section of the
ISDN Basic Rate Interface: Features (553-3001-380).
After you have completed the setup to perform acceptance testing, proceed
with the tests described in "Testing ISDN BRI functions" on
ISDN Basic Rate Interface
