1. GENERAL
This practice provides installation and operational
procedures for the ADTRAN‚
Remote 1xN Pro-Cap
protection switch multi-mount housing (P/N
1190860L1). See Figure 1. Pro-Cap initiates remote
switching of a DS1 or HDSL circuit to a standby line
following detection of a fault. This eliminates the
immediate need for a vehicle dispatch to investigate
trouble or provide standby service. The shelf also
accommodates DDS and ISDN technologies but
without protection.
Figure 1. 1xN Pro-Cap
Pro-Cap can be used in conjunction with the
®
ADTRAN Total Access
3000 Carrier Class
Broadband Multiservice Access
Platform, or any standard Office Repeater Bay (ORB)
with T1 or HDSL to provide a Protection Switching
Network Interface (PSNI).
The Pro-Cap housing accepts eight T200 type circuit
cards or four dual slot T400 DS-1, HDSL, or HDSL2
circuit cards. The unit is a wall mounted assembly
that provides convenient access to CPE connections.
The assembly incorporates a circuit board backplane
that provides a choice of amphenol connector or
wire-wrap pins for facility wiring hook-up.
The Pro-Cap accepts -48 VDC local power or a
modular power supply that inserts into the POWER
slot at the far right of the shelf. The power supply
module includes an AC power cord that plugs into a
standard 110 VAC grounded outlet.
The Switch Customer Interface Module (SCIM) can
mount to either the left or right side of the Pro-Cap
housing to facilitate access to all CPE connections.

161190860L1-5B Section 61190860L1-5, Issue 2
The SCIM can be locally powered by -48 VDC, or
span powered from the standby unit in slot 8 if
equipped for span power. Slide switch S1 selects
between local or span power. CPE receive and
transmit connections are either amphenol or RJ-48C
jacks.

Physical Description
The 1xN Pro-Cap consists of four elements:
1. Mounting-Plate
The mounting-plate attaches to a customer
premises backboard.
2. Shelf
The shelf has slots for seven channel modules,
one standby (protect) module, and one power
module, plus two external edge connectors for
the SCIM. The power terminal strip has
connections for power, alarm, and ground. The
shelf attaches to the mounting-plate.
3. Switch Customer Interface Module
This module inserts into one of the SCIM edge
connectors located on either side of the shelf. It
has both amphenol and RJ-48C interface
connections to the customer loop. Behind an
access panel is a power connection terminal
strip, a slide switch for either span or local
power, protect ON/OFF switch, and a
pushbutton for selecting individual module
protection or resetting the protect configuration.
Selection and status is indicated with associated
LEDs on the SCIM front panel.
4. Housing Cover
The Plexiglas swing door housing cover
encloses the shelf allowing viewing and access
to the shelf modules.
Functional Description
During normal customer and network transmission,
data is transported through the active modules in slots 1
through 7. The module in slot 8 is the standby
(protect) unit. If a fault is detected on an active line a
series of facility initiated manual commands switch the
standby module to an active mode in place of the
faulted unit. When the faulted unit malfunction is
resolved another series of manually initiated
commands (or the reset switch) returns it to active
service and the standby unit is returned to standby
status. The LED bank shows module status during
normal and standby conditions. When circuit
protection mode is disabled the Pro-Cap unit can be
used as a standard 8-slot T200 mounting.
Auto-Protect Switching
When the Pro-Cap is used in association with the
ADTRAN Total Access 3000 platform, certain Total
Access 3000 cards initiate an automatic protect
function with the Pro-Cap. These cards send the same
protect enable/disable, arming, and switching codes as
sent in the manual switching mode. The Pro-Cap does
not require configuration changes to support the
auto-protect feature. The same configuration
supporting manual switching also supports automatic
switching. Additional information is in Section 9 of
this practice.
Listed here are Total Access 3000 cards that initiate the
auto-protect codes:
• H2TUC 1181112L5
• H2TUR 1222026L7
• H2TUR 1221026L7

provides information on implementing the auto-protect
function.
LED Indication
Table 1 describes LED indication.
• All LEDs OFF indicates no power to the SCIM.
• All LEDs flashing red indicates the protect card is
disabled and SCIM power is local -48 VDC.
2. INSTALLATION
C A U T I O N
SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
!
After unpacking the unit inspect it for damage. If
damage is noted, file a claim with the carrier then
notify ADTRAN. Refer to Warranty and Customer
Service.
Mounting Procedure
The 1xN Pro-Cap installs at the remote location using
the following procedure:
NOTE
All component fasteners are spring-loaded,
captured thumb screws.
3. The shelf assembly lifts away from the mountingplate by disengaging the chassis tabs from the
mounting-plate support hooks.
4. Using the mounting-plate as a template, position
the mounting-plate at the desired location and
mark four pilot holes. Ensure the unit is level and
that cable plugs will reach their designated
sockets.
5. Using an appropriate bit, drill the four pilot holes.
6. Align the mounting-plate to the pilot holes and
attach to the wall with appropriate fasteners.
7. Reassemble the unit by reversing steps
1 through 3.
Cable Connections
Frame Ground
Both the shelf and SCIM have separate ground
connections. Each must be connected to a known
approved ground location. Verify metal to metal
contact on all connections and ensure ground circuit
continuity.
The shelf has various openings for wire route options
along with tie-wrap anchor points and extrusions for
securing cables and connectors.
Specific wiring arrangements are customer developed.
CAUTION
1. Remove the housing from the shelf by unscrewing
the two thumb screws on the side of the housing.
The housing pulls out and away from the shelf.
Transmit and receive loops to both facility and
CPE have two connection schemes. Only one
connection method is to be used, not both.
2. Remove the shelf from the mounting-plate by
unscrewing the thumb screw at the top center of
the shelf bay. It is not necessary to remove the
SCIM assembly unless its position is to be
reversed to the other side of the shelf.
Facility Side
Amphenol Connection – The to-facility and
from-facility amphenols can be either left-side or
right-side oriented.

Wire-Wrap – The to-facility and from-facility
wire-wraps are an alternate method in lieu of the
amphenol connections.
Customer Side
Amphenol Connection – The to-CPE and from-CPE
amphenols should be left-side oriented to prevent
SCIM panel removal interference after amphenol
installation.
RJ-48C – These modular jacks are an alternate method
in lieu of the amphenol connections.
Shelf Cards
Channel cards are individually configured to meet
network or customer requirements. Certain cards only
receive power from network span power. These cards
do not have pin contacts for shelf power.
CAUTION
It must be determined if channel cards can receive
both span power and shelf power. Some cards
may malfunction under that condition.
-48 VDC Terminal
Local DC power connects to terminal strip TB1 at the
bottom of the shelf backplane. This power source is
distributed across the backplane to slots 1 through 8
and can jumper to the SCIM TB1 to power the
controller card.
NOTE
Both the shelf backplane and the SCIM card each
have a TB1 terminal strip. This practice identifies
the specific TB1 when referenced in the text.
3. CONFIGURATION
Shelf
There are no configuration selections on the shelf
backplane. If -48 VDC is connected to TB1 on the
shelf card there is no need for the power card unless
for a spare power source.
Power Card
The PWR card has an AC power cord that inserts into
a standard 110 volt AC grounded wall outlet. When
AC power is in use, local power should not be
connected to TB1 on the shelf card. The PWR card
also applies power to the same TB1 shelf terminals,
which in turn can be jumpered to TB1 on the SCIM
card.
SCIM Controller Card
Option switches on the SCIM controller circuit board
are located behind an access panel. Remove the
housing from the shelf to gain access to the panel’s
thumb screw fastener (refer to Step 1 of the Mounting
Procedure). See Figure 2 for SCIM Card connections,
terminals, indication, and switches.
Protect Card
The protect card can receive power from either the
Figure 2. SCIM Card Elements
network (span) or from the backplane (-48 VDC). To
initiate the protect feature the card in slot 8 must
support the technology of the channel cards that are
enabled for protection. The protect card should also
have span power capability to power the SCIM should
that configuration be used.
