4-Wire TO provides for two individual 4-wire analog
interfaces between a VF transmission facility and the
Total Access 1500 Pulse Coded Modulation (PCM)
backplane. Each TO interface provides 4-wire
voice-grade (analog) data services with no signaling
associated with the circuit, or where signaling is
provided by in-band tones.

-40ºC to +65ºC
• TLP transmit input range of +5.0 to -16.0 dBm in
0.1 dB increments
• TLP receive output range of +8.5 to -9.5 dBm in
0.1 dB increments
• Supports configurations for Sink, Source or No
Sealing Current
• Provisioning by craft interface or Site Manager
• Digital Loopback and 1004 Hz Digital Reference
