ThinMux Chassis January 3, 2002 1
OVERVIEW
The ADC®ThinMux™chassis houses the ThinMux DS3 or ThinMux STS-1
multiplexer and fits in a Central Office (CO) rack. Each type of multiplexer
provides support for a minimum of 28 T1 (or 21 E1) lines from the chassis.
The chassis also provides two DS3 interfaces for external equipment. It
features a forced-air cooling unit, Ethernet port, rear craft port, craft ports on
the multiplexer front panels, and fiber management guides. Offering a 1+1
protected multiplexing function on the network and client side, the ThinMux
chassis is the industry’s most compact multiplexer platform.
FEATURES
•The ThinMux chassis allows for the following shelf configurations:
–STS-1 to 28 T1 (using ThinMux multiplexer HXU-359)
–DS3 to 28 T1 or 21 E1 lines (using ThinMux multiplexer HXU-360)
•Dual multiplexer support for 1+1 protection of network and customer
interfaces
•Migration path and investment protection on installed equipment
•Concentration of many low-speed access network interfaces to a single
high-speed network interface
•Industry-standard 64-pin T1 (or E1) connectors enable rapid installation
•Craft port access for easy configuration
•Field-serviceable forced-air cooling unit
Depending on your network interface requirements, several cabling options
are available. Select the instructions that apply to your configuration as
shown in “Installing DS3 or STS-1 Interface Cables” on page 11.

EXTERNAL INTERFACES
The ThinMux chassis provides the following interfaces:
•T1/E1
•T1/E1 Test
•RS-232
•10/100BASE-T Ethernet
•Discrete alarms
T1/E1 INTERFACE
There are two female 32-pair connectors to access 28 T1 (or 21 E1) lines for
intra-building connection; no protection is provided on the backplane. One
connector is for transmission, the other is for reception. Each port is routed to
both multiplexers (A and B) for transmit and receive. See “Appendix A - Pin
Assignments” on page 14 for interface pinout description.
T1/E1 TEST INTERFACE
The four-wire test interface can be routed to any of the 28 T1 (or 21 E1)
low-speed T1/E1 ports. It can be used to monitor the line or to look toward
the network or subscriber drop. The four signals are accessed through
four 0.045-inch wire-wrap pins. (For more information about the wire-wrap
pins, see “Connect Test Access” on page 9.)
A shielded 32-pair cable should be used and grounded at
either the frame or chassis. The ground connection is done at
one end of the cable only to avoid ground loops.
External Interfaces LTPH-UM-1088-02, Issue 2
4 January 3, 2002 ThinMux Chassis
RS-232 CRAFT INTERFACE
Communication with the ThinMux STS-1 and ThinMux DS3 central
processors occur through a standard grounded DB-9 connector (RS-232 Data
Communication Equipment interface).
Signals are routed to both multiplexers, and the transmitter of the inactive
multiplexer remains in a tristate mode. Pin 5 is the digital ground of all digital
components (both multiplexers). See Table 3 on page 17 for interface pinout
description.
10/100BASE-T ETHERNET INTERFACE
Communication with the multiplexer (STS-1 or DS3) central processors
occurs through the standard grounded RJ-45 10/100BASE-T interface for
metallic chassis. Similar to the RS-232 interface, signals are routed to both
multiplexers; the transmitter of the inactive multiplexer remains in a tristate
mode. See Table 4 on page 17 for interface pinout description.
DISCRETE ALARMS
In addition to the various interfaces supplied by the ThinMux chassis, the
common access panel (see Figure4onpage8) provides access for discrete
alarm wiring.
The discrete alarms connection is provided by 0.045-inch wire-wrap pins
located on the rear of the chassis (see Figure 1 on page 2). The signals are
routed to the multiplexers, where the logic functions are performed. Critical
VIS and AUD alarms comprise dry contacts for telemetry applications. The
alarms have an independent common connection (serial COM port) to relays;
normally open (NO) is provided. Current is limited to 0.5A when a maximum
temperature rise of 20°C on traces is desired (as per MIL-STD-275C).
When using a legacy HXU-358 multiplexer, the CRIT VIS, CRIT AUD, and
Alarm pins must be left unconnected. For all other multiplexers, these pins
may be used as needed.
Other alarms (FE, MIN, MAJ, and CRIT) share the same COM, and only
normally open contact is provided as shown in Figure4onpage8. Contact
closure is made using a solid-state relay photo Metal-Oxide Semiconductor
LTPH-UM-1088-02, Issue 2 Installation
ThinMux Chassis January 3, 2002 5
Field-Effect Transistor (MOSFET). When set to ON, resistance is 35Ωat
85°C (worst case). The switched current must be less than 80 mA, and the
switched voltage must be less than 135V. If a coil relay or other inductive
load is used, a protection diode must be connected between the alarm signal
and the COM signal to prevent damage to the solid state relay. ADC does not
provide the diode with the ThinMux chassis. The diode must be purchased
separately. Use Motorola diode part number 1N4004 or equivalent.
BATTERY SUPPLY
The battery supply terminals are located on the rear of the chassis under the
common access panel (see Figure 1 on page 2). Five AWG 16 wires connect
the Return B, -48B, Return A, -48A, and Frame Ground to the power source.
To wire power A and B inputs, attach A and B power leads from the fuse
panel or office battery to the appropriate screw connector on the terminal
block. For more information, refer to “Connecting Power” on page 10.
INSTALLATION
Before installing the ThinMux Chassis, visually check its
packaging to ensure that it has sustained no shipping
damage. Immediately report any damage to the shipping
agent. See “Appendix C - Product Support”on page 19.

12-24 x 1/2screws in each bracket and secure the chassis to the rack.
Two sets of mounting brackets are supplied to fit 19-inch or
23-inch racks with standard EIA-hole spacing (1/2 inch).
Optional brackets with WECO-hole spacing (1 inch) are
available (ACE-MK1).

WIRING THE COMMON ACCESS PANEL
1Unscrew the common access panel hold-down lugs and remove the cover
(see Figure 4).
Figure 4. Wire-Wrap Pin Positions/Common Access Panel (rear view)
Connect a BITS Timing Source
2Determine if you require a BITS timing source connection to the chassis;
if so, the chassis must first have a line termination prior to chassis
connection.
The BITS concept is used for interoffice synchronization distribution.
Each line source, Bits A and Bits B, must be terminated. ADC provides
this termination through external termination blocks (product catalog
TERM-100) placed on wire-wrap terminal posts on the rear of the
ThinMux chassis as shown in Figure 5 on page 9.

INSTALLING DS3 OR STS-1 INTERFACE CABLES
After mounting the chassis to the CO rack, select the appropriate interface for
cable installation. (For information regarding multiplexer configuration and
operation, refer to the specific multiplexer user manual.)
The ThinMux chassis DC power supply feeds must be
connected to either (1) -48 Vdc Safety Extra Low Voltage
(SELV) sources or (2) -48 Vdc sources that are electrically
isolated from the AC sector and reliably connected to earth.
The source’s fault current capacity shall be lower than 50A,
or an appropriate overcurrent protection, rated 5A, must be
provided on each -48 Vdc conductor. The overcurrent
protection can also be used as a cutoff switch if another
disconnect device is not installed.
The ThinMux chassis is configured for redundant power.
The A and B battery sources are independently connected
to each multiplexer. In the event of a loss of power from
one of the sources, an alarm is reported by the active
multiplexer. Power is continually supplied to both slots in
the chassis.
When installing components, wear an antistatic wrist strap.
Avoid touching components on the circuit board.
