Facility Loopback: A 1 enables an E1 facility (side) loopback for port n.
The E1 transmit clock and data output signals are looped back internally as
the E1 receive clock and data input signals. The external E1 receive input
signals are disabled. The E1 transmit clock and data output signals are pro-
vided at the interface.
Line Loopback: A 1 enables an E1 line (side) loopback for port n. The
receive E1 clock and data output signals are looped back internally as the
E1 transmit input signals. The external E1 transmit clock and data input sig-
nals are disabled. The E1 receive clock and data output signals are pro-
vided at the interface.
Send Receive E1 Line AIS for Port n: A 1 enables an E1 AIS (unframed
all ones signal) to be inserted into the receive data stream for port n inde-
pendent of the status of the internal alarms.
Transmit E1 Line AIS for Port n: A 1 enables an E1 AIS (unframed all
ones signal) to be inserted into the transmit data stream for port n indepen-
dent of the status of the internal alarms.
Transmit VT AIS for the TU/VT Selected for Port n: A 1 enables a TU/VT
AIS to be transmitted for the TU/VT selected. A TU/VT AIS consists of all
ones in the entire TU/VT, including bytes V1 through V4.
Transmit Port n RFI (Remote Failure Indication): A 1 enables an RFI
alarm to be transmitted (bit 4 in the V5 byte is set to 1).
Transmit Port n RDIS (Remote Server Defect Indication): A 1 enables an
RDIS to be transmitted (bit 8 in the V5 byte is set to 1, and bits 5, 6 and 7 in
the K4 (Z7) byte are set to 101).
Transmit Port n RDIP (Remote Payload Defect Indication): A 1 enables
an RDIP to be transmitted (bit 8 in the V5 byte is set to 0, and bits 5, 6 and
7 in the K4 (Z7) byte are set to 010).
