Emulated channel
units
2-4 Issue 4 June 2002
The SLC ConnectReach system can emulate up to a maximum of six quad
channel units (24 voice circuits) with a mix or combination of any of the following
types of channel units. As an example, the SLC ConnectReach system could be
configured with all six channel units as SPQ
could be a mixture of two SPQ440(C,D), two SPQ452, and two SPQ456 channel
units.
All of the channel units will be specified in the SLC ConnectReach system
configuration menu, but they must also be provisioned and administered at the
SLC-2000 HDT.

SPQ 440C Channel Unit (SPOTS
The SPQ440C channel unit is a quad SPOTS channel unit that provides two-wire
current feed (CF) voice capability and supports both loop-start and ground-start
signaling. The SPQ440C channel unit is emulated by software in SLC
ConnectReach systems prior to Software Release 5.0.1 and is used for analog
voice channels and secondary/fractional-T1 voice lines (TR-08 and TR-303).
NOTE:
The SLC ConnectReach system will not be able to implement all of the test
capabilities of the SPQ440C channel unit; however, the SLC
ConnectReach system will respond to test messages with stable
responses.
®
SPQ 440D Channel Unit (SPOTS
The SPQ440D channel unit is a quad SPOTS channel unit that provides two-wire
current feed (CF) voice capability and supports both loop-start and ground-start
signaling. The SPQ440D channel unit is emulated by software in SLC
ConnectReach systems with Software Release 3.6.3 and later and is used for
analog voice channels and secondary/fractional-T1 voice lines (TR-08 and
TR-303). The SPQ440D additionally supports the voice frequency data
enhancement (VFDE) feature that allows the SLC ConnectReach system to
operate in the clear channel mode.
NOTE:
The SLC ConnectReach system will not be able to implement all of the test
capabilities of the SPQ440D channel unit; however, the SLC
ConnectReach system will respond to test messages with stable
responses.
