UR399
UL Listed Central Office Connector
Key Features
Description
• Maximum density saves space;
increases number of protected
cable pair per frame vertical
The UL Listed UR399 is the highest density 100-pair connector available that uses industry
standard 5-pin protector modules. Its compact design, only 8.5-in. (216mm) H x 4-in.
(104mm) W x 10-in. (257mm) D, allows maximum density per frame vertical.

Business-Critical Continuity
™
• Narrow block width permits
large inter-vertical working space
for fast, convenient jumper
administration
• Front ground test point saves labor
and increases reliability; provides
a convenient place to attach an
alligator clip without reaching
behind the connector
• Accepts industry standard
protector modules to permit a
wide module selection
• Gold-plated protector module
sockets and test field contacts
provide superior electrical contact
to eliminate noise problems
• UL Listed for documented
performance
The UR399 has a metal shroud that fully encloses the rear of the block (Fig. 1) and is UL
Listed to meet specification number UL 497.
Made of a polycarbonate-blend, connectors can be factory stubbed with 22- or 24-gauge
cable in 10-ft. increments, starting at 20 feet. The internal protector module ground
system is constructed of ten 12AWG copper ground rods interconnected to two 6AWG
copper ground bars, which are perpendicular to each other. The grounding system is
attached to a ground link that protrudes out of the left of the shroud (Figs. 2 and 3). The
assembled portion of this 6AWG ground link determines the ground classification of a
UR399 connector as either:
(a) standard or frame ground system
catalog prefix UR399 (Fig. 2)
(b) isolated module ground system
catalog prefix USR399 (Fig. 3)
Front and rear snap-through fanning strips facilitate orderly jumpering and offer highly visible pair count identification. The 100-pair front-facing test field makes testing easy.
The UR399 meets or exceeds the specifications set forth in the Telcordia TA-EOP-000164
and GTE GTS 8339 documents.
Application
The UR399 protects personnel and
equipment from abnormal voltages
and currents on incoming cable pairs. It
mounts on central office conventional
frames with 8-in. centers and RDS modular frames from Emerson , or PBX where
UL Listed circuit protection is required.
