2. External is used only for Kentrox shelves. Unit transmits 12-volt p-p to DSX panel.

3. Latching Loopback Mode

• T1 - When optioned for T1 mode, the unit does not respond to DDS Latching Loopback codes.

• FT1 (Fractional T1) - DDS Latching Loopback operation is supported. The H2TU-C units which are in the

HDSL circuit are treated as Identical Tandem Data ports and the HTU-R is treated as a different Tandem

Data port.

Note: When operating in FT1 mode and during periods of T1 loss of signal, LOS, or T1 AIS from the customer

CI, the HDSL system will send in the network direction from the HTU-C a Fractional DS1 idle signal

consisting of a repeating 7E (HEX) byte payload within a framed/unframed T1 signal. In addition,

when optioned for FT1 mode, the setting for Customer Loss Response is ignored.

4. Customer Loss Indicator

• AIS - Send AIS to network upon T1 loss of signal or T1 AIS from customer.

• LPBK - HTU-R initiates a network loopback upon T1 loss of signal or T1 AIS from customer.

• AIS/CI - HTU-R sends customer disconnect indication upon loss of signal, loss of synchronization, or receipt

of T1 AIS from customer.

Note: The CI is generated by transmitting the framing received from the network while overwriting the

payload with a repeating pattern. For applications where the DS1 is Extended Superframe, the data

link is overwritten with a Yellow Alarm that is interrupted once every second by a 100 milli-second

code burst of 7E (HEX).

5. Shelf Alarm is on the DDM+, 3192M, and 3192 Units only.
