The SCIM can be locally powered by -48 VDC, or span powered from the standby unit in slot 8 if equipped for span power. Slide switch S1 selects between local or span power. CPE receive and transmit connections are either amphenol or RJ-48C jacks.

Revision History

Issue 2 adds Auto-Protect information when the Pro-Cap is configured in a Total Access 3000 network.

Features

The 1xN Pro-Cap includes these features:

•Protection module.

•Compact and lightweight assembly that accommodates eight T200 mechanics or four T400 mechanics modules.

•Reversible SCIM for right side or left side assembly.

•Prewired backplane to minimize wiring errors and installation time.

•Protect module can function as standard channel module.

•Dedicated slot for modular power supply.

•LEC facility connections are made by 25-pair Amphenol XMT/RCV connectors or wire-wrap pins.

•CPE connections are made to RJ-48C modular jacks or 25-pair Amphenol XMT/RCV connectors.

•Auto-Protect Switching with Total Access 3000 applications.

•Swing open tinted Plexiglas front cover.

•Available with key-locking metal cover (List 4 Option).

•Includes standard 10-year warranty.

Physical Description

The 1xN Pro-Cap consists of four elements:

1.Mounting-Plate

The mounting-plate attaches to a customer premises backboard.

2.Shelf

The shelf has slots for seven channel modules, one standby (protect) module, and one power module, plus two external edge connectors for the SCIM. The power terminal strip has connections for power, alarm, and ground. The shelf attaches to the mounting-plate.

3.Switch Customer Interface Module

This module inserts into one of the SCIM edge connectors located on either side of the shelf. It has both amphenol and RJ-48C interface connections to the customer loop. Behind an access panel is a power connection terminal strip, a slide switch for either span or local power, protect ON/OFF switch, and a pushbutton for selecting individual module protection or resetting the protect configuration. Selection and status is indicated with associated LEDs on the SCIM front panel.

4.Housing Cover

The Plexiglas swing door housing cover encloses the shelf allowing viewing and access to the shelf modules.

Functional Description

During normal customer and network transmission, data is transported through the active modules in slots 1 through 7. The module in slot 8 is the standby (protect) unit. If a fault is detected on an active line a series of facility initiated manual commands switch the standby module to an active mode in place of the faulted unit. When the faulted unit malfunction is resolved another series of manually initiated commands (or the reset switch) returns it to active service and the standby unit is returned to standby status. The LED bank shows module status during normal and standby conditions. When circuit protection mode is disabled the Pro-Cap unit can be used as a standard 8-slot T200 mounting.

Auto-Protect Switching

When the Pro-Cap is used in association with the ADTRAN Total Access 3000 platform, certain Total Access 3000 cards initiate an automatic protect function with the Pro-Cap. These cards send the same protect enable/disable, arming, and switching codes as sent in the manual switching mode. The Pro-Cap does not require configuration changes to support the auto-protect feature. The same configuration supporting manual switching also supports automatic switching. Additional information is in Section 9 of this practice.

Listed here are Total Access 3000 cards that initiate the auto-protect codes:

• H2TUC 1181112L5

• H2TUR 1222026L7

• H2TUR 1221026L7

1xN specifications

ADTRAN 1xN is a significant innovation in the realm of broadband network technology, designed to enhance the capacity and efficiency of data transmission in various communications infrastructures. This technology is particularly beneficial for service providers looking to upgrade their existing networks in an economically viable manner.

One of the primary features of ADTRAN 1xN is its ability to support multiple optical network terminals (ONT) from a single fiber source, which drastically reduces the amount of infrastructure required for deployment. This one-to-Many approach allows network operators to extend their service reach while minimizing the cost associated with laying down extensive fiber networks.

ADTRAN 1xN utilizes both Passive Optical Network (PON) and Active Optical Network (AON) technologies. The PON technology grants high-speed data transmission rates, accommodating several service tiers and customer demands, while the AON provides enhanced flexibility and control over data flows for network administrators. This dual-faceted approach enables operators to choose the best deployment strategy to meet specific user needs, whether in residential, commercial, or enterprise environments.

Another characteristic of this technology is its scalability. Providers can easily integrate ADTRAN 1xN into existing networks without needing extensive overhauls, allowing for easy upgrades as customer demand for service increases. This feature ensures that investments in infrastructure remain relevant and capable of handling increased data loads over time.

Additionally, ADTRAN 1xN offers robust support for various applications, including Voice over Internet Protocol (VoIP), streaming media, and cloud computing solutions. The network’s architecture effectively prioritizes data traffic to ensure quality of service, critical for users relying on real-time communications.

ADTRAN also emphasizes energy efficiency in its 1xN solutions, aligning with global sustainability initiatives. By minimizing power consumption while maximizing performance, ADTRAN not only meets operational needs but also helps service providers lower their overall environmental impact.

In conclusion, ADTRAN 1xN stands out as an inventive and flexible solution for modern broadband service providers. With its combination of advanced optical technologies, scalability, extensive application support, and commitment to energy efficiency, it represents a significant advancement in delivering high-quality, reliable internet connectivity.
