4. INSPECTION
Inspect the equipment thoroughly upon delivery. If the equipment has been damaged in transit, immediately re-
port the extent of damage to the transportation company.
Wescom equipment is identified by a model and issue number imprinted on the front panel or located elsewhere
on the equipment. Each time a major engineering design change is made on the equipment, the issue number is
advanced by one number on any subsequent models that are manufactured. Therefore, be sure to include both
the model number and its issue number when making inquiries about the equipment.
Each module is shipped in static-protective packaging to prevent electrostatic charges from damaging static-sen-
sitive devices. Use approved static-preventive measures, such as static-conductive wrist straps and a static-dissi-
pative mat, when handling modules outside of their protective packaging. A module intended for future use should
be tested as soon as possible and returned to its original protective packaging for storage.
Do not ship or store modules near strong electrostatic, electromagnetic, or magnetic fields. Use the
original static-protective packaging for shipping or storage.

5. MOUNTING
The 3192–9E is fully qualified for operation in a –40 to 65
_
C temperature range, and can be deployed in outside
plant electronics cabinets or indoor building Remote Terminals, typically in Wescom Span Termination System
(STS–3192) Mounting Shelves.
Complete the optioning in Part 6 before installing the 3192–9E unit into a shelf or assembly.
Installation and removal of modules should be done with care. Do not force a module into place. If
excessive resistance is encountered while installing a module, remove the module and check the
card guides and connector to verify proper alignment and the absence of foreign material.
CAUTION
6. OPTIONS
6.1 SI—Power Mode
S1 (see Figure 6) is a 3-position slide switch used to select CI side power modes: line powering (PWR), sealing
current (SC), and looped simplex (LP).
6.1.1. Line Powering, S1 = PWR
In this mode the 3192–9E provides an Automatic Span Power Regulator (ASPR) circuit that automatically gener-
ates up to 96V of regulated span voltage at a constant 60mA of current. This power source can be used to power
the customer’s CSU and/or intermediate span line repeaters as long as the total voltage drop does not exceed 96
volts or 1600 ohms of equivalent simplex resistance at 60mA. Note that the customer’s terminal equipment (CSU)
plus wiring can require up to 68V per FCC P.68 rules.
6.1.2. Sealing Current, S1 = SC
In this mode the 3192–9E provides approximately 12mA of sealing current toward the customer equipment. The
CPE equipment must be locally powered and should be optioned to provide a looped simplex path toward the
3192–9E.
6.1.3. Looped Simplex, S1 = LP
In this mode the 3192–9E loops the CI side simplex leads. This mode can be used if the CPE equipment provides
a sealing current source toward the network, or if no sealing current is provided across the interface.
