LED Description

The UTA220 has six LED indicators: B1, B2, D, DP, T, PW.

The functions of these LEDs are as follows:

B1 - On when the B1 channel has a call.

B2 - On when the B2 channel has a call.

D- This LED is for the D-Channel.

•It is off when the U connection is not established.

•It single blinks when the U connection is established. (This may take up to 15 seconds after connection is made.)

•It double blinks when communications are established with the switch.

•It is on when all B channels are available.

DP - On when the D-Channel is available for packet calls.

T(Test) - On during the following global tests:

• 2B+D loopback

•Switch initiated tests--quiet mode and insertion loss measurement

PW - On when the UTA220 has power.

FUNCTIONAL

The UTA220 operates on the ISDN Basic Rate Interface (BRI) (2B+D). This interface provides two 64-kbps full-duplex bearer (B) channels for circuit switched lines. The Basic Rate Interface also provides a 16 kbps delta (D) channel for signaling messages. The UTA220 adapts any data terminal to the ISDN Basic Rate Interface for circuit-switched data.
