AS420 T1/E1 Loopback Device

The AS420 is a stand-alone, T1/E1 smart digital loop device that resides between T1/E1 customer premises equipment (CPE) and the T1/E1 network termination unit (NTU) at the customer site. The AS420 facilitates T1/E1 performance management visibility so that NSPs can troubleshoot network circuits end to end. The AS420 accomplishes T1/E1 access diagnostics via payload maintenance loops that are locally or remotely activated. The AS420 offers quick and easy configuration via DIP switches.

Highlights

• Flexible BNC or RJ-48C network and CPE interfaces (autosensing)
• LED status indicators for power, bipolar violations, CRC errors, network status, loop status
• Payload maintenance loops-on-demand locally or remotely
• Power bypass relays to ensure network uptime
• Supervisory port for unit management upgrades
