for your reading pleasure from the docs:
The following conditions apply to this feature:
• The PRI card requires the SX-200 ELx Cabinet Rev 4.4 or greater (9109-600-002-NA) with LIGHTWARE 17 Release 4 or greater.
- Software releases of LIGHTWARE 17 Release 3.1 or less do not recognize the PRI card. The PRI card and the ISDN Network Gateway are both programmed as an ISDN bay/node type in Form 1; however, the ID of a PRI card differs from the ID of an ISDN Network Gateway, thereby allowing the system to differentiate between the two bays.
• In a main control cabinet, the PRI card fits into slots 10 or 11 and does not require a FIM II or CIM on the PRI card. The dip switch (S1 switch) settings on the PRI card must be set to 1 closed and 2 open. The backplane of the SX-200 ELx cabinet Rev 4.4 or greater (9109-600-002-NA) provides the link signals.
Note: Only one PRI card can be installed in a control cabinet. This restriction allows the ISDN bay to be within the power budget. Two PRI cards can be installed in a peripheral cabinet.
• In a peripheral cabinet, the PRI card fits into slots 10 or 11 and requires a FIM II or CIM on the PRI card to connect to the FIM or CIM in the main control cabinet. The dip switch (S1 switch) settings on the PRI card must be set to 1 and 2 closed.
• The system identifies the PRI card as a peripheral bay, even though you install the PRI card in a cabinet already defined as a bay.
• The PRI card is not included in the high power card count since it is regarded as its own peripheral bay.
• In a main control cabinet, the PRI card in slot 10 is Bay 2; a PRI card in slot 11 is Bay 4. A PRI card can never be a Bay 1.
• In a peripheral cabinet, the PRI card will have the bay number that corresponds to the numbered position of the FIM termination at the main control cabinet. Therefore, a PRI card can be a Bay 2, 3, 4, 5, 6, or 7 depending on the FIM link that is being used on the Control FIM.
• The PRI Card supports up to 2 T1 links. Only one dual T1 module is allowed on the PRI card.
• Installation of PRI cards is Slot 10 or 11 does not restrict the peripheral interface cards in slots five and six.
• Purchasable MOSS options enable the following in the PRI card(s): Q.SIG (option 86), NFAS (option 91), D -Channel Backup (option 92), Remote LAN Access (option 93), Min/Max (option 94), and Auto Min/Max (option 95). Option 91 to 95 are downloaded to each PRI card installed. These MOSS options serve all the PRI cards in the system. If you change any of these options, you must reset the PRI card to enable them, and you may need to download a new IMAT database on to the PRI card(s).
Note: Min/Max is required to program Auto Min/Max and NFAS is required to program D-Channel Backup.
• You must purchase the MOSS option, Number of Links (option 96). This option enables the number of T1 links on the PRI card and the BCC III. This option has no effect on the ISDN Network Gateway.
