2-Wire Unbundled ISDN Digital Loops will be provisioned
according to industry standards for 2-Wire Basic Rate ISDN
services and will come standard with a test point, Order.
Coordination, and a DLR. Network Telephone Corporation will be
responsible for providing BellSouth with a Service Profile Identifier
(SPID) associated with a particular ISDN-capable loop and end
user. With the SPID, BellSouth will be able to adequately test the
circuit and ensure that it properly supports ISDN service.
BellSouth will not reconfigure its ISDN-capable loop to support
IDSL service.
The Universal Digital Channel (UDC) (also known as IDSLcompatible
Loop) is intended to be compatible with IDSL service
and has the same physical characteristics and transmission
specifications as BellSouth’s ISDN-capable loop. These
specifications are listed in BellSouth’s TR73600.
The UDC may be provisioned on copper or through a Digital Loop
Carrier (DLC) system. When UDC Loops are provisioned using a
DLC system, the Loops will be provisioned on time slots that are
compatible with data-only services such as IDSL.
2-Wire ADSL-Compatible Loop. This is a designed loop that is
provisioned according to Revised Resistance Design (RRD)
criteria and may be up to 18kft long and may have up to 6kft of
bridged tap (inclusive of loop length). The loop is a 2-wire circuit
and will come standard with a test point, Order Coordination, and
a DLR.
2-Wire or 4-Wire HDSL-Compatible Loop. This is a designed loop
that is provisioned according to Carrier Serving Area (CSA)
criteria and may be up to 12,000 feet long and may have up to
