Ordering T1-PRI (Primary Rate ISDN) Service for Dialogic® Brooktrout® TR1034 Fax Board

When you order T1-PRI service from the telco or service provider, provide the following information:

Product Manufacturer: Dialogic Corporation (formerly: Brooktrout Technology)
Product Name: Dialogic® Brooktrout® TR1034+yxH-T1 Fax Board (where 'x' denotes the number of channels active on the card, ie: 4, 8, 16, 24 and "y" denotes for 'P' for PCI and 'E' for PCIe)
Signal Protocol (or 'trunk type'):  Common Channel Switching
Frame Mode: Extended Super Frame
Line Coding: B8ZS
Clock Master:  The switching device providing the PRI line to the Brooktrout TR1034 Fax Baord must act as NETWORK / Clock Master, or pass master clock signal seamlessly from PSTN.  The Brooktrout TR1034 Fax Board(s) must act as TERMINAL end / User Side. 
Number of Channels:  24 (23 "B" channels plus one "D" channel, commonly written "23B+D") 
B Channel Provisioning:  Circuit-Switched Voice & Data
B Channel Service: Voice; as fax is considered voice, the line would be configured as though voice calls were being placed over it.
D Channel Service: Signaling only with the D-channel on channel 24 of the T1-PRI line.
Packet Handlers: No packet handlers other than the D-channel. 
Channel Service: 64Kbps clear channel service end-to-end for every call.
Compatible Switch Types: Your telco or service provider needs to tell you the type of switch that is providing the PRI line to the Brooktrout TR1034 Fax Board; the list of supported switch types is: 4ESS, 5ESS, DMS100, DMS250, Ericsson MD -100(North America), Ericsson MD -110 (International), Siemens (North America), Japan
Compatible Variant Types:  Your telco or service provider needs to tell you the program variant programmed on the PRI line; the list of supported variant types is: AT&T Pub41449, National ISDN1, National ISDN2, NorthernTelcom NIS A211-1
Called Party Number:  This is what the ISDN world calls 'DID' or 'DNIS'. Normally the last 4 digits of the number dialed; required for  inbound routing. Please confirm with your telco or service provider the number of CPN digits it will be providing to you on inbound calls.

If the total number of digital channels on the Brooktrout TR1034 Fax Board(s) will not allow for all 23 B-channels to be utilized (for instance, if you are using a Brooktrout TR1034+P/E4, 8, or 16H-T1 Fax Board, where 'x' denotes number of activated channels on the board), you will need to tell to your telco or service provider which B-channels you will be using. Then, the telco or service provider will not direct traffic to B-channels that are not mapped to functioning Brooktrout TR1034 Fax Board channels. This is sometimes called a 'fractional PRI'  or 'partial PRI '  line .
