LTPH-UM-1088-02, Issue 2 Overview 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.

LTPH-UM-1088-02, Issue 2 External Interfaces 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.
External Interfaces LTPH-UM-1088-02, Issue 2 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.
LTPH-UM-1088-02, Issue 2 Installation Field-Effect Transistor (MOSFET). When set to ON, resistance is 35Ω at 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.

(Mounting brackets and screws are contained in the installation kit.
LTPH-UM-1088-02, Issue 2 Installation INSTALLING THE FAN MODULE (FB1) Fan module ThinMux chassis Figure 3. Installing the Fan Module (FB1) 1 Unwrap the enclosed fan module. 2 Align the fan with the slot located on the left side of the chassis and slide the fan in as shown in Figure 3. 3 Insert the fan module until the connector is firmly seated in the backplane.

Installation LTPH-UM-1088-02, Issue 2 Connect Alarms 6 Connect the alarm relay wires from the CO alarm center to the posts of the Visible Alarm (CRIT. VIS—NO and COM), Audible Alarm (CRIT. AUD—NO and COM) and Alarm (FE, MIN, MAJ, CRIT, and COM). Follow the CO site instructions for connecting alarm relays. The visible and audible alarm relays do not have an NC (normally closed) position. 7 Connect a 16 AWG chassis ground cable to the ground (GND) post.
LTPH-UM-1088-02, Issue 2 Installation 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.
