DUAL CHANNEL E1 SHORT HAUL LINE INTERFACE UNIT
FUNCTIONAL DESCRIPTION
23
December 12, 2005
In the receive Dual Rail mode, the CDR unit can be by-passed by setting
R_MD[1:0] to ‘11’ (binary). In this situation, the output data from the Data
Slicer will be output to the RDPn/RDNn pins directly, and the RCLKn out-
puts theexclusive OR(XOR) of theRDPnand RDNn. Thisis calledreceiver
slicer mode. In this case, the transmit path is still operating in Dual Rail
mode.
3.3.9
RECEIVE PATH POWER DOWN
The receive path can be powered down individually by setting R_OFF
bit (RCF0, 09H...) to ‘1’. In this case, the RCLKn, RDn/RDPn, RDNn and
LOSn will be logic low.
In hardware control mode, receiverpower down can be selected by pull-
ing RPDn pin to high on a per channel basis. Refer to 5 HARDWARE CON-
for more details.
3.3.10 G.772 NON-INTRUSIVE MONITORING
In applications using only one channel, channel 1 can be configured to
monitor the data received or transmitted in channel 2. The MONT[1:0] bits
(GCF, 20H) determine which direction (transmit/receive) will be monitored.
The monitoring is non-intrusive per ITU-T G.772. Figure-9 illustrates the
concept.
The monitored line signal (transmit or receive) goes through Channel
1’s Clock and Data Recovery. The signal can be observed digitally at the
RCLK1, RD1/RDP1 and RDN1. If Channel 1 is configured to Remote Loop-
back while in the Monitoring mode, the monitored data will be output on
TTIP1/TRING1.
