Front Panel LEDs

The Total Access 1500 Dual 4-Wire TO has two front panel LEDs that provide status information for each interface. See Table 4 for LED indications.

4. TEST FEATURES Initiated Tests

The Dual 4-Wire TO supports a Digital Network Loopback and 1004 Hz Tone Tests for each port to support circuit turnup and maintenance efforts. These tests are initiated from the Total Access Site Manager or the Total Access 1500 Local Craft Port on the SCU, and are initiated on an individual port basis.

Digital Network Loopback Test

The Digital Network Loopback provides a loopback path for the DS0 data from the network. Received data of the selected port is latched in on the appropriate receive time slot on the receive bus, and then placed on the transmit bus in the appropriate port’s transmit time slot.

1004 Hz Tone Test

The 1004 Hz Tone Test generates a 1004 Hz @

0 dBm Digital Reference Signal (DRS) tone, which is used to send DRS signal to the loop, to the network, or to both simultaneously.

The Total Access 1500 Dual 4-Wire TO requires no routine maintenance for normal operation.
