Select the cable label sheet (Figure 2-7) that identifies the cabinet
(blue for #1, orange for #2, and green for #3).
On an octopus cable, attach an appropriate label (CAB1 SLOT8, for
example) on the last flag-type cable tie and on the back of the hood
of the 25-pair connector.
Connect the 25-pair connector end of the octopus cable to an
appropriate receptacle (ZTN79) on the switch cabinet.
Run the octopus cable horizontally through the D-rings and mount it
on the 50A Fanning Strip as shown in Figure 2-31.
Repeat the previous steps for each ZTN79 receptacle, so that all
octopus cables linking 7300H Series terminals to the cabinet are
labeled and run to the 50A Fanning Strip.
Check the Voice and Data Station Records Form to see which SIP
adapter jacks are connected to 7300H Series terminals.
Connect port 1 of the first ZTN79 to the primary attendant console.
Connect port 2 of the same CP to the primary attendant’s Direct
Extension Selector (DXS) console (if present).
Connect the remaining plugs on the octopus cable to other 7300H
Series terminal SIP jacks. Connect other ZTN79 CPs to other 7300H
Series terminal adapters. Distribute the 34-button Deluxe and BIS
terminals equally among all ZTN79 circuit packs.
Fill in the port ID of each station on the Voice and Data Station
Records Form (Figure 2-26).
