Aculab is in the process of seeking approval by JATE for connection to public primary rate ISDN
as specified in this appendix, and the 'Instructions for Use' subject to the conditions set out in
these documents.
Usage and Type
The T1 card is principally designed for use connected to a 1544 Kbps integrated services digital
network (primary rate ISDN) with INS signalling, but other types of private circuit use are also
appropriate, and other signalling systems are available or planned.
The Approval will only be applicable when the T1 card is used with Aculab supplied signalling
software appropriate for the Approval.
The file to be loaded into RAM for signalling software to connect to the network is
INS_USR.P4R
for rev 1.5 PM’s or
INS_USR.UPR
for rev 2 PM’s

Speech Calls
If the T1 card is used in an application that makes or answers calls with a service code that
indicates a speech or telephony call, or any call that may use a partly analogue route, there is a
requirement that audio signals transmitted are encoded using CCITT
µ
-law PCM, and do not
exceed a 1 minute mean power level of -12dBm.
Many of the speech and FAX resource cards that may be used with the T1 card comply with this
requirement, but it is the responsibility of the user to ensure that this requirement is complied
with, by confirmation via the manufacturer of the card, or by any other suitable means such as
independent testing.
Signal sources that do not in themselves guarantee compliance with this requirement must be
conditioned by appropriate circuitry before transmission.
Card Installation & Connection
Safety Warnings
Interconnection circuits should be such that the equipment continues to comply with the
requirements of 2.3 of EN 60950 for SELV circuits, after making connections between circuits
using any of the internal ports.
Refer to a competent telecommunications engineer before installation and connection to the
network is made.
