This section explains how to order an ISDN PRI line for your Dialogic Diva PRI Media Board.
What to order
Specify the following requirements when you place your order:
23 B-channels + 1 D-channel
D-channel on channel 24 (timeslot 24). Do not order NFAS (non-facility associated signaling service), which enables you to use channel 24 as a data-carrying B-channel.
Layer 1 line code is B8ZS with ESF (Extended SuperFraming)
Data rate of 1.544 Mbps
64 kbps clear channel service which ensures calls will not be routed over 56 kbps channels
Companding type is µ-law
A CSU is not required (the Dialogic Diva Media Board supplies the function of the CSU internally). However, you can connect to a CSU if present.
A DSU is not required (the Dialogic Diva Media Board supplies the function of the DSU internally).
NOTE
Dialogic Diva V-1PRI PCIe HS, V-2PRI PCIe HS, V-4PRI PCIe HS, V-4PRI PCIe FS and V-8PRI PCIe FS Media Boards do not supply the function of the CSU or the DSU internally. You need to purchase it from an independent distributor.
The T1 interface number must be 0.
The D-channel must be specified as the terminal endpoint identifier (TEI) 0.
If the switch type is AT&T/Lucent, request that allocation of channels for incoming calls is in descending order, high to low (23 to 1).
Information to obtain when you order
Obtain the following information when you place your order. You will need this information to properly configure your Dialogic Diva PRI Media Board.

Directory or phone number assigned to the PRI line.
Line build out setting (LBO). Only if you are going to use the Diva Media Board's on-board CSU.
Number of DNIS (Dialed Number Identification Service) digits provided by your service provider. Normally, you can choose between four, seven, or ten digits.
NOTE
Dialogic Diva V-1PRI PCIe HS, V-2PRI PCIe HS, V-4PRI PCIe HS, V-4PRI PCIe FS and V-8PRI PCIe FS Media Boards do not supply the function of the CSU or the DSU internally. You need to purchase it from an independent distributor.
