T-APS – END TO END PROTECTION

T-APS – End to End Protection

Protect your T-Span with a pair of automatic protection switches. Both links are continuously monitored and the switches coordinate switching, so you are never out of sync. Use a rack mounted, multi-switch system at the host location and standalone units at the customer premise or remote office.

T-APS – REDUNDANT CPE EQUIPMENT

T-APS – Last Mile Redundancy

If you have redundant feeds to your facility these switches will insure you are always on the best option. Both feeds are monitored you set the parameters for automatic switching. Of course you always have control via network management.

T-APS – REDUNDANT CPE EQUIPMENT

T-APS – REDUNDANT CPE EQUIPMENT

The T-APS series protects redundant equipment as well as redundant T-Spans. Back-up redundant routers, channel banks, or call center systems with these layer 1 reliable switches. Let Dataprobe application engineering show you how to integrate system reliability into any system.

  • Backup Switching On Autopilot

    T-APS switches make redundancy switching easy. The T-APS continuously monitors T-1 or E-1 circuits and switches to the operational path, and provides automatic failover switching between redundant lines.

    Designed for both line protection and equipment redundancy, the T-APS is ideal for any T-1 and E-1 networks where downtime is not an option. With the T-APS in control, you can have peace of mind that your critical applications will stay up and running.

  • Simple Programming to Onsite Applicaitons

    The T-APS is ideal for small offices and customer premise applications. It’s a self-contained, standalone unit capable of being powered by A/C or 48VDC sources, and line connections are standard RJ45 T1 and E1 (120 Ohm) connections. The T-APS features complete manageability via terminal or SNMP manager, plus status relay alarms.

    With the T-APS, small offices can enjoy the same T-1 / E-1 circuit protection as larger enterprises.

  • Multiple Circuit Switching Options

    With the T-APS rack mount card and chassis system, you can provide T-1 / E-1 protection to multiple circuits. All of the features of the standalone T-APS are supported in the card version, but up to 15 primary/redundant circuits can be supported.

    Each T-APS-R card provides a complete independent T-1 / E-1 protection switch, and all cards are managed from one network or serial interface with simple web pages and telnet menus.

    The chassis supports either 48VDC or 120/240 VAC with external power supplies. T-1 / E-1 terminations are via RJ45 Modular Jacks.
