Safety Warnings and Notices LTPH-UM-1088-02,Issue 2

SAFETYWARNINGS ANDNOTICES

The ThinMux chassis DC power supply feeds must be connected to either (1) -48Vdc Safety Extra Low Voltage (SELV) sources or (2)-48Vdc 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-48Vdc conductor. The overcurrent protection can also be used as a cutoff switch if another disconnect device is not installed.

This equipment may be provided with a module that incorporates laser source(s). Refer to the module’s documentation for detailed safety information.

The telemetry I/O must be connected to either a SELV source or an ELV source that is electrically isolated from the AC sector and reliably connected to earth.

The metallic telecommunication interface should not leave the building premises unless connected to telecommunication devices providing primary and secondary protection.

Overview

 

 

OVERVIEW

The ADC® ThinMuxchassis houses the ThinMux DS3 or ThinMuxSTS-1multiplexer 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 aforced-aircooling 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-1to 28 T1 (using ThinMux multiplexerHXU-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-speedaccess network interfaces to a singlehigh-speednetwork interface

Industry-standard64-pinT1 (or E1) connectors enable rapid installation

Craft port access for easy configuration

Field-serviceableforced-aircooling 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.

The ThinMux chassis provides a compact 1U platform for the ThinMux family of multiplexers with the following interconnects:

One 10/100BASE-TEthernet (IEEE 802.3)

Two 64-pinfemale receptacle connectors for T1/E1 transmit/receive,chassis-shielded

Four 75BNC connectors forDS3/STS-1transmit/receive

Four wire-wrap0.045-inchpins for Building Integrated Timing Supply (BITS) A and B

Four wire-wrap0.045-inchpins for T1 or E1 test access, transmit/receive

Four wire-wrap0.045-inchpins for Visible (VIS) and Audible (AUD) alarms (dry relay contacts) which are normally open (NO) discrete alarms

Five wire-wrap0.045-inchpins for discrete alarms (solid sate relay contacts): Far End, Minor, Major, and Critical

Five screw connectors for -48Vdual power
