Remote Cable Pair Switching System (RECAPSS)

From cable transfers to redundant network routing, RECAPSS is the solution.

In today's communications world, the growing bandwidth of the digital services offered to customers is increasing. Transferring circuits to fiber or providing a redundant physical layer back-up route is essential. Now that local network competition has embarked the demand for lower costs and better service has come full circle.

Utilizing RECAPSS will...

Save You Money... by allowing craft personal to work more efficiently. No need to revisit the splice each time for every special circuit release. Fewer times in and out of splices mean fewer changes of introducing a problem.

Improve Customer Service... by eliminating the need for craft personal to keep handling the network. Once RECAPSS is installed, you will never need to touch the splice again, unless you want to reuse the RSU at a different location.

Transfer Circuits in Milliseconds... means less down time for your customers

Proven in the field technology, RECAPSS units are in service throughout the United States, with Telephone Companies, Commercial and Residential users and the US Military, as well as in Canada, Europe, and the Pacific Rim.

RSU-RM Data Sheet

Remote Switch Units (RSUs)

Each switch in a Remote Switch Unit (RSU) connects a Input pair (C) to either an Primary pair (A) or a Secondary pair (B) without interrupting service to the customer. The switching between the Primary or Secondary side is preformed by the Commander Control Software package. The Commander Control Software package, Commander for short, runs on a Windows95 PC with a modem.

The system accommodates all circuit types suitable for twisted copper pairs. An operator can transfer one pair at a time or select groups of pairs with just one button. In the case of trouble with the secondary pair, the user can rapidly put it back.

With three different switch styles and many different packaging options the reusable RSUs repay their initial cost many times over.

Features

• Suitable for all types of environment (aerial, buried, indoor, in-splice and underground applications)
• Housed in either:
  • Standard 19/23" rack mounted housing
  • Sealed PVC case, pressurized through a standard "F" valve
  • Encapsulated in a polyethylene case
• Available in sizes from 25 to 2100 pairs
• Combine as required to handle any size job
• Powered and controlled from the Control Unit (CU) over a control pair, one pair per 100 switches
• Powered ONLY during transfer
• No need for constant commercial power or battery backup
• Transfers tip and ring conductors simultaneously
• Switches are double pole, latching, with a transfer time of 3 msec
• Available in three models, each tailored to the type of switching that will be performed

Specifications

Remote Switch Units (RSUs)

Switch Arrangement: Switches are arranged in 100 switch modules. Each module uses a single control pair to individually address and actuate each switch. Modules are assembled in case sizes from 100 to 2100 switches.

Switching Speed: Approximately 3 switches per second during cutovers.

Switching Time: 3 msec nominal

Switch Type: 2 Form C, latching, sealed, meets FCC Part 68 breakdown requirements.

Power Requirements: During switching, the Control Unit supplies power over the control pair. When idle, switch positions are maintained without power or battery backup.

Loop Limit: 2000W

Operating Temperature: -40 C� to +80 C�

Minimum Switch Life: 100 million cycles @.1 Amps, 50VDC

Cable Stub: Standard color coded poly insulated conductors (BKMH & BKTH)

Surge Protection: All switched circuits are protected against voltage surges up to 1500V. Surges greater than 1500V require external protection.

Control Unit (CU)

Switching Capacity: 10,000 switches (fully equipped) 1000 switches per Line Relay card, up to 10 Line Relay cards per (CU)

Power Requirements: 110VAC,60Hz, 1 Amp maximum; 220VAC, 50Hz, 1 Amp maximum

Operating Temperature: 0 C� to +50 C�

Telephone Line: CU has screw terminals for telephone line used to communicate with the Commander Control Software.

Commander Control Software

Disk Space Requirements:

• 5MB free hard drive space for system files
• Additional space for database files (1MB = 5,000 switch records)

Computer: Microsoft Windows95 compliant

Recommended

• Pentium 133 or better
• 16MB of RAM
• 1G hard drive
