System
The SLC ConnectReach system is hosted off of a SLC-2000 remote terminal/host
digital terminal (RT/HDT). The SLC ConnectReach system appears to the
RT/HDT as a SLC-2000 multiservices distant terminal (MSDT) with its associated
backplane interface unit (BIU) and channel units (CUs). The SLC ConnectReach
system communicates with the SLC-2000 RT/HDT over the same T1 line 4-kb/s
data link channel used by the MSDT. The SLC ConnectReach system will also
respond to inventory request messages for the BIU and CUs just as an actual
plug-in unit does. The SLC ConnectReach system interfaces with the SLC -2000
RT/HDT by means of a distant terminal (DT) Server plug-in unit that is located in
the SLC-2000 metallic distribution shelf (MDS). Channel units must be
provisioned and administered at the SLC-2000 RT/HDT just as they are for an
MSDT.
Each SLC-2000 RT/HDT can serve a maximum of 1,152 customer DS0s (four
MDS assemblies x two MDSs per MDS assembly x 12 DT Server cards per
MDS x 12 DS0s per DT Server card = 1,152 DS0s).
The SLC-2000 RT/HDT metallic distribution shelf (MDS) assembly is comprised
of two metallic distribution shelves that contain slots that normally accept SLC
channel unit cards. However, when the RT/HDT is serving a SLC ConnectReach
system, a DT Server card is installed in the MDS instead of channel unit cards
and the MDS is provisioned for fiber in the loop (FITL). In general, metallic
channel units cannot be used with DT Servers on the same MDS.
