1. OVERVIEW

The Service Interface Protection Panel (SIPP), Model

SIPP-1800, is a modular and easy to configure interface

that protects network transmission equipment exposed to

outside plant facilities. Advanced technology in the SIPP

provides greater protection to network equipment than

conventional methods. Applications include central

offices, CEVs, and outside plant cabinets - wherever

protection from lightningsurges and AC power faults is

needed.

The base SIPP-1800 model is an 18-slot chassis that

accepts plug-in modules to terminate and protect dry-loop

Ethernet, T1/E1, or DS3 services. A fiber interface

module (without protection) is also available, allowing all

high-speed services to be groomed through a single

access panel. A choice of connector configurations

provides added flexibilityand utility. The SIPP can be

installed in arelay rack or cabinet, or wall mounted.

2. APPLICATION

Multiplexers, switches and other network elements that

are connected to outside plant facilities require protection

from excess voltage or current that could cause damage

to equipment or injure personnel.

A common method is to install voltage-limiting primary

protectors on network ports and a separate service panel

for connection to outdoor facilities. The shortcomings of

this approach are: 1) voltage limiting alone may not

adequatelyprotect some types of network equipment,

2) wiring to separate protector blocks and service panels

is space consuming and cumbersome, and 3)many

applications require fuse links to prevent risk of fire,

shock, or potential damage to the service panel.

The SIPP resolves these issues by combining service

panel convenience with advanced protection of personnel

and equipment (seeFigure 2). The integrated solution

meetsrigorous telecom network standards, simplifies

wiring, and saves valuable space.

The versatility of the SIPP makes it suitable for any

combination of Ethernet, T1/E1, DS3, or fiber services in

central offices, CEVs, or outside plant cabinets.

Orderable options allow for front-only or front and rear

access to connectors.

NOTE: For dry-loop service only (no DC voltage).

3. DESCRIPTION

The base SIPP-1800 model is an 18-slot chassis, 1RU

high, with adjustable brackets for rack or wall mounting.

The chassis is constructed of heavy-gauge stainless steel

and accommodates up to eighteen plug-in modules, as

described below.

Plug-in Modules

Service Protection Modules (SPM) connect to copper

facilities to protect Ethernet, DS3, or T1/E1 network

equipment against lightning surges and AC power faults.

Modules are available with front-only or front and rear

connectors, and optional monitor jacks. Each SPM

occupies one or two slots in a SIPP chassis, depending

on the chosen jack configuration.

Figure 3. Example Service Protection Modules

Fiber services or copper services that do not require

protection can beconnected through a Modular Interface

Panel (MIP), shown in Figure 4. The MIP module

occupies four slots in a SIPP chassis and provides four

Keystone slots for snap-in couplers that connect network

equipment to facilities.

Please refer to the Ordering Guide at the end of this

documentfor a list of plug-in modules and their

descriptions.

Coordinated Protection

The Service Protection Modules combine current limiting,

voltage limiting (gas discharge tube), and fusing to

prevent lightning and AC surges from damaging network

equipment.Figure 5 shows the placement of these

protection elements within the SPM.

Figure 5. SPM block diagram

The fast-reacting current limiter blocks transients by

switching to a highresistance state, at which point the

gas tube diverts surge energy to ground. The

combination of current and voltage limiting blocks more

energy than can be achieved by voltage clamping alone.

Within one microsecond, the current let through toward

network equipment is reduced to less than 1 mA(0.1V

into a 100Ωload). After the surge clears, the current

limiter returns to a low series resistance and the gas tube

returns to high bridging resistance.

Fail Safe Operation

Fusing within the SPM provides an alternative to

installation of external fuse links. In the event of an

extreme lightning surge or high AC exposure, SPMfuses

opens to prevent hazardous damage to connectors or

cabling. The fuses are surge tolerant and remain

transparent to moderate strikes.

In addition, all SPM gas tubes include a fail-short

mechanism that prevents thermal overload under AC

conditions. The feature creates a mechanical short to

ground and only operates if prolonged AC energy exists

that could otherwise create a fire hazard.

Activation of a fuse or fail-short mechanism requires the

SPM to be replaced.

disconnected after the module is removed from the

mounting. Loosen the screw on the module’s front panel

and slowly slide the unit forward out of the chassis, being

careful to guide anycables connected to the rear.

MIP-4 Couplers

The MIP-4 module accepts snap-in Keystone style

couplers for fiber, coaxial, or twisted pair terminations that

do not require protection.

NOTE: Couplers are installed or removed from the rear

of the MIP-4 with the module removed from the chassis.

Each coupler is held in place by angled tabs along the top

and bottom of the coupler body. To install a coupler, tilt it

back slightlywhile inserting it though the rectangular

opening, until the lower tab clears the front of the panel.

Then apply pressure to the upper tab and tilt the coupler

bodyforward until itsnaps in place.

To remove a coupler from the MIP-4, apply pressure to

the upper tab while tilting the coupler bodybackward.

After the upper tab is freed, the coupler can be lifted and

removedfrom the opening.

WARNING

When removing a module or its LINE connection:

Visuallyinspect the cable and equipment for damage or

exposed conductors BEFORE making contact.

Use appropriate detection equipment to ensure that no

hazardous voltages or currents are present.

Follow local guidelines for safety.
