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 in the Brooktrout configuration tool.
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 in the Dialogic® Brooktrout® configuration tool.
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.

NOTE: 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 .
