DBS-2.3/9.2-400
1. Not available with CPC-AII.
2. Ground Start lines perform similarly to Loop Start; however, in terms
of positive disconnect signals, Ground Start lines provide the most
reliable connection between the CO and the DBS, with the least
possibility of call collision or "glare".
3. The Ground Start Trunk Card (VB-43531) is required for ground-start
operation.
4. The Ground Start Trunk Card requires a -48 volt power supply, which
must be properly connected to the DBS backplane terminals -- see
Section 300-Installation for instructions. Misconnection of the power
supply can result in serious damage to DBS equipment.
5. The FLASH and REDIAL features are not available on ground-start
trunks.
1. Not available with CPC-AII.
2. Available only with CPC-B Version 2.0 or higher.
3. Requires DID Trunk Card (VB-43541).
4. Requires SCC-B card Version 1.27 or higher.
5. DID (Direct Inward Dialing) lines are beneficial in that the CO can
place multiple inbound trunk calls (with different phone numbers) over
the same circuit. These numbers can also be programmed to appear on
multiple DBS extensions.
6. DID circuits can only be used for inbound calls (not for outbound).
7. The DBS supports 4-digit DID numbers with either Dial Pulse or
(more commonly) Wink Start.
1. Not available with CPC-AII.
2. Available only with CPC-B Version 4.0 or higher.
3. T1 requires the following cards:
• T1 Interface (VB-43561)
• T1 MDF Card (VB-43562)
• T1 Sync Card (VB-43563)
4. When assigning trunks as Circuit Type "T1", you must start from the
highest-numbered trunk port in the DBS cabinet structure, and move
down sequentially from there. For more information, see the trunk
assignment charts in the T1 Reference Manual (Section 500).
