Total Access 3000 Hi-Cap RT Solution

Arrangement

The Hi-Cap RT Solution consists of a Emerson MESA Bridge cabinet that receives two 
customer provided DS3 feeds that enter the cabinet through the sealed fittings at the bottom 
of the End Chamber and terminate to the DS3 Protection Chassis. 
The DS3 signals are then routed through the DS3 Protection Chassis, delivered to the DS3 
NIU3 3-Slot Chassis via coax and BNC connectors, and then routed to the Total Access 3000 
shelves via coax and BNC connectors. Total Access 3000 Shelf 1 subtends Shelf 2 via RJ-485 
connectors. 
Each Total Access 3000 shelf multiplexes 28 DS1 services (HDSL, HDSL2, HDSL4, or legacy 
T1) for a total of 56 circuits. The Total Access 3000 DS1 services originate from the 64-pin 
Champ connectors on the Total Access 3000 backplane and terminate to the Equipment-side 
of the Cross-Connect Panel. Loop 1 pairs are wired sequentially to positions 1 through 56. 
Positions 57 through 100 are not connected. Loop 2 pairs are wired sequentially to positions 
101 through 156. Positions 157 through 200 are not connected. 
The customer is responsible for making the wire-wrap jumper connections between the 
Equipment-side and Field-side of the Cross-Connect Panel. For more information, refer to 

“Cross Connections” 

on page 23.

The Field-side wire-wrap pins of the Cross-Connect Panel are terminated to the 200-pair 
Protector Block wire-wrap pins. The customer is responsible for providing and inserting 
protection modules for active circuits. For more information, refer to 

“Protection Modules” 

on 

page 23.
The Protector Block is terminated to eight 25-pair MS2 Splice Modules. The customer is 
responsible for making the connection between the factory assembled MS2 splice modules 
and the customer or field loop. For more information, refer to 

“Outside Plant Wiring” 

on 

page 23.
