The Super II Frame is dimensionally compatible
with Porta Systems' CAM Frames, as well as existing AT&T modular protector frames. Its
use as an adjunct to a main distribution frame provides additional space for future
growth. Individual Super II Frames may be connected together to form a larger frame
assembly. There is no direct limit to the number of frames that may be connected, other
than space consideration.
This family of Porta Systems connector blocks
is designed to terminate and protect outside plant cable pairs on central office,
CPE,
carrier and special service distributing frames. Included are features for identifying
cable and pair counts, testing and special service integrity, in addition to current and
voltage strike protection by means of plug-in protector modules.
The critical parameters that must be considered in the selection of
connectors in this family group are:
- Connector block physical dimensions (height,
width, depth).
- Connector block cable pair termination capacity.
- Type of protector modules required.
- Stubbing arrangements.
- Test access capabilities.
Connector Block Features
All Porta Systems connector blocks are
made of flame-retardant Lexan plastic fastened to a rugged universal mounting bar,
compatible with a wide variety of vertical frame hardware. Each connector block is
equipped with wire wrap terminals for the termination of outside plant cable pairs and
either wire wrap or quick-clip "punch on" terminals for jumper cross connection
wires. Continuity between the two pair termination fields is achieved by means of the
protector module. Each block is equipped with an array of five terminals for each outside
plant cable pair. Four terminals provide a tip and ring continuity between the outside
plant pair and the jumper wire while the fifth terminal serves as a ground connection as
well as a polarization guide.
Included on the connector block is an integral
fanning strip to dress and identify the jumper wires. Connector blocks vary in
vertical height from a minimum of 5" (12.7 cm) for the 10-pair connector block to 9"
(22.9 cm) for the 508
series and 11 " (for the 503 type. Widths, which control inter-vertical work areas are
critical in 7" vertical center applications. They vary from the 3.74" (9.5 cm)
width of the side administered 508P Connector to the 5" (12.7 cm) width of the front
administered 508PC1 Connector, with the protector modules included.

Protection
The plug-in protector modules are
compatible with the entire family of connector blocks, providing a wide variety of
protection, including carbon block, gas tube or solid-state high voltage protection with
or without heat coils for sneak current protection.
Porto Systems' patented innovations provide
faster response time and longer operational life - a "radial" carbon in the
carbon block voltage protector modules, a "delta diode" in some gas tube
modules, and a solid state chip in solid state modules.
Porta Systems solid state protector module is
specially designed for use with sensitive digital equipment.
The protector modules feature various internal
circuit configurations for numerous special purpose applications and are manufactured in a
complete line of color coded base and handle combinations. The encapsulated modules
completely enclose all components, ensuring the elimination of service interruption caused
by accidental disturbances.
Testing
Test cords and front tap shoes are
available for use with all connectors, permitting a single craft person, working a lone,
to fully identify and completely test up to 100 outside plant cable pairs. Individual test
cords are available for testing and fault locating via the integrated test points built
into the protector modules.
Stubbing
Cable stubs of 22 or 24 gauge are
furnished in various lengths upon request. The cables are provided with a gas-tight
pressure plug and can be ordered in either a "stub up" or "stub down"
position. The 100 pair cable stub has a PVC sheath with tinned 22 or 24 gauge wire. The 22
gauge stub has a nominal outside diameter of 1.0" (2.54 cm) and the 24 gauge stub is
1.0" (2.54 cm).
When the cable entering the central office is
"exposed" to possible contact with lightning or power conductors operating at
voltages above 300 volts, the wires in the stub cable of the connector should be at least
two gouges larger than the wires in the entrance cable or fusing link. (A stub cable of 22
AWG wire should be used when a fuse link or entrance cable is 24 AWG or finer).
Main Frame Application
All connector blocks are designed for
standard "B" type main frame applications, with the outside plant cable
terminated directly on the connector block with the protector modules providing continuity
through to the cross connection terminations.
Wire Terminations
All outside plant cable pair
terminations are designed for single wire wrap terminals. On the cross connection side of
the connector blocks, a variety of pin terminations are available including single wire
wrap, bifurcated wire wrap, 66 -type clip punch-on, twin clip bifurcated punch-on and
tribeam bifurcated punch-on. Customized Amphenol type plug arrangements are also
available, in addition to special terminal pin arrangements for cutover applications.
