Canadian EMC Requirements
This Class A digital apparatus meets all requirements of the Canadian interference-causing
equipment regulations.
Cet appareil numerique de la Classe A respecte toutes les exigences du reglement sur le materiel
brouilleur du Canada.
Usage and Type
The Prosody cPCI card is principally designed for use connected to a 1544 Kbps T1 service
configured for primary rate ISDN (PRI) with National ISDN 2 signalling. Other types of private
circuit use are also appropriate, and other signalling systems are available or planned.
Below are examples of the files to be loaded into RAM for signalling software to connect to the
network:
Revision 2 PM
Revision 1.5 PM
NI2_USR.UPR
NI2_USR.P4R
(for NI-2 T1 PRI)
ATT_TUSR.UPR ATT_TUSR.P4R
(for AT&T, TR41459, T1 PRI)
T1RB.UPR
T1RB.P4R
(for robbed bit T1)

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.
Many of the speech and FAX resource cards that may be used with the T1 card comply with this
requirement. 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 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 UL60950-1 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.
