RDDU
RCVR Data Distribution Unit
RDI
Remote Defect Indicator. Previously known as Far End Receive Failure (FERF).
RDI
Ring Drop/Insert (Add-Drop)
RDSV
Running Digital Sum Violations
Receive-direction
The direction towards the cross-connect.
REGEN
Regenerator
Regenerator Loop
Loop in a network element between the Station Clock Output(s) and one or both Station
Clock Inputs, which can be used to dejitterize the selected timing reference in network
applications.
Regenerator Overhead Controller (ROC)
SLM circuit pack that provides user access to the SDH overhead channels at repeater
sites.
Regenerator Section Termination (RST)
Function that generates the Regenerator Section Overhead (RSOH) in the transmit
direction and terminates the RSOH in the receive direction.
REI
Remote Error Indication. Previously known as Far End Block Error (FEBE). The REI
reflects the number of BIP-8 violations that were detected in the B3 of the incoming
signal on a per frame basis.
Relay Unit (RU)
Radio Relay circuit pack whose main function is to perform protection switching when
the Alignment Switch in the demodulator unit is unable to perform protection switching.
Restore Timer
Counts down the time (in minutes) during which the switch waits to let the worker line
recover before switching back to it. This option can be set to prevent the protection
switch continually switching if a line has a continual transient fault. This field is greyed
out if the mode is non-revertive.
Revertive Switching
In revertive switching, there is a working and protection high speed line, circuit pack,
etc. When a protection switch occurs, the protection line, circuit pack, etc. is selected.
When the fault clears, service reverts back to the original working line.
