INSTALLATION
INSTALL MODULAR BULK POWER SUPPLY
(Optimal)
The 346 Modular Bulk Power Supply (MBPS) is a cost-effective and flexible
alternative to the KS-2291 1 power supply. The 346 MBPS can be used
where the wall-mounted (outlet) KS-2291 1 power supply cannot be used or
where multiple KS-2291 1 power supplies are required.
The 346 MBPS consists of the 346A Power Unit and 346A1 Power Panel. Up
to three 346A Power Units can be mounted in a power panel. Each 346A
Power Unit is capable of powering four terminals with adjuncts (“1 O w“
position), for a total of 12 terminals.
Terminals powered by the 346A Power
Unit can be located up to 1000 feet from the unit.
The 346 MBPS should be installed near the SIP. Service to the ac outlet
powering the 346 MBPS must be a dedicated (nonswitched) 20-ampere line.
A maximum of four power panels can be connected to the 20-ampere line.
The AC Surge Suppressor (T11 Model 428) should be used with the 346A1
Power Panel.
INSTALL EQUIPMENT ROOM TRUNK CABLING
As mentioned earlier, all outside lines must be connected to the system
through connectorized network interfaces. These interfaces are connected to
wall-mounted trunk access equipment (TAE), and from there to the cabinets.
Connect Network Interfaces to TAE Blocks
The trunks and off-premises stations from the network interface must be cut
down on the TAE’s connecting blocks so that the trunks are grouped by type
(loop start, ground start, DID, and tie) at the connecting block. Each
connecting block can handle up to three groups of eight trunks or two groups
of four tie trunks.
Each group can contain only one type of trunk. For loop start, ground start,
and DID trunks, the first group of eight trunks goes to leg 1 of the splitter
cable; the second group of eight trunks goes to leg 2; and the third group of
eight trunks goes to leg 3. For tie trunks, the first group of four trunks goes
to leg 1 of the splitter cable; and the second group of four trunks goes to leg
2.
