RLH Industries 16 Channel T1 Over Ethernet Multiplexer System User Manual - 2.2 Function Description
In the reverse direction, packets from the uplink ports are sorted at the switch unit. All but T1/E1
packets are passed to the local data ports. The packets containing T1/E1 data are sent to the TDM/
Packet processing unit for reassembling the original data stream, and recovering the T1/E1 clock which
is the key element of the device. Very sophisticated algorithm is used to ensure that the reconstructed
clock will meet the stringent requirement of TDM applications. The most important parameters are jitter,
wander, and signal delay.
The control unit interfaces with the user through console port so that various operational parameters can
be modified.

Front panel
The T1/E1 modules and power supplies are accessible from the front panel. The modules are secured to
the chassis with thumbscrews. To remove a module for servicing, unscrew the retainers, then insert two
of the thumbscrews into the threaded holes in the front panel of the module you wish to remove. Screw
the retainers in fully, and the desired module will be separated from the chassis far enough for easy
removal by hand.
