HotWire 7924-A1 Models and Features
Products in the HotWire 7924 family provide “last mile/last kilometer” transport of
T1-compatible circuits between customer facilities and central site equipment
over 2- or 4-wire copper lines. The units can be used over distances substantially
exceeding traditional T1 spans and Canadian Standards Association (CSA) loop
standards.
HotWire 7924 standard features include:
V.35 or DSX-1 interface
Full support for T1 using two twisted-copper pairs
Full support for fractional T1 using one or two twisted-copper pairs
Automatic detection and compensation for inverted pairs and swapped loops,
which simplifies installation
Tolerance of bridged taps
Local and remote alarm surveillance
Local and remote T1 network and HDSL loop performance monitoring
HotWire 7924 may be ordered either as a standalone unit (7924-A1-xxx) or as a
nest-mounted card (7924-B1-xxx) that fits in a HotWire 7900 nest. This guide
describes the installation and maintenance procedures for the standalone
version, Model 7924-A1-xxx.
Up to ten standalone units may be installed in an optional HotWire 7900 10-Slot
Standalone Shelf. This is a convenient way to stack standalone units, using a
single power source.
