Ideal for Customer Premise Applications
Small offices can now benefit from the same T1 and E1 circuit protection that larger sites employ. Protect your critical voice and data circuits with dual redundant circuits, automatically switched with Dataprobe's T-APS Protection Switch
The T1/E1 Protection Switch, model T-APS provides automatic failover switching between two redundant lines. It continuously monitors both T1 or E1 circuits and switches to the operational path, based on user defined criteria.
The T-APS is ideal for customer premise installations. It is a self-contained, standalone unit capable of being powered by A/C or 48VDC sources. 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. A LCD display and front panel buttons and LED indicators allow complete local programming, status monitoring and manual control.

Rack Mount Multi-Circuit Chassis
Provide T1/E1 protection to multiple circuits with this card/chassis system. Up to 15 primary/redundant circuits can be supported in the rack mount chassis. Each T-APS-R card provides a complete independent T1/E1 protection switch. All cards are managed from one network or serial interface with simple web pages and telnet menus.
All of the features of the standalone T-APS are supported in the card version.
The chassis supports either 48VDC or 120/240VAC with external power supplies. T1/E1 terminations are via RJ45 Modular Jacks.
