MIX 56 User Manual SSEMBLIES Front Panel Each MIX 56 chassis houses two independent systems, System 1 and Sys- tem 2. The front of each system is equipped identically (with the exception of one electrostatic discharge (ESD) jack per chassis), and either system can be used as a DSX only, as a nonredundant multiplexer, or as a redun- dant multiplexer.
To use a system as a multiplexer with full DSX capabilities, connect incom- ing and outgoing DS1 signals to the front wire-wrap pins. LEDS The LED status indicators on the MIX 56 front panel are grouped into the following categories: •...

ALERT! MIX 56 is not intended to be connected directly to out- side plant (OSP) leads—install behind a listed NT1-type device. 122188-10 A0 Telect, Inc.
Each configuration varies in weight depending on the number and type of chassis’ and cables used. If bay weight exceeds the floor support capacity, computer floor supports can be ordered from Telect (part # 071-6000-3001/ 3002 for one or two panels respectively).
–48 Vdc at 1 amp, or 24Vdc at 2 amp. The panel must be acces- sible when operating the unit. The chassis must receive 20Vdc to 60Vdc. Since MIX 56 includes active components, Telect recommends using a dual feed panel to provide input power redundancy.
These procedures may be modified to agree with site practices or operating company procedures. If you are installing the optional MIX 56 Broadband Sidecar (PN 747-9999-2001), read the installation instructions included with the kit before installing the MIX 56 chassis.
Repeat steps 2 and 3 on the other side of the chassis. Rack-Mounting the Chassis A single MIX 56 chassis requires 5.25 in. of vertical space (the height of the chassis). When installing one chassis on top of another, install a heat baffle of at least one rack unit above and below the pair.
Page 29
MIX 56 User Manual Step Action Loosely mount the chassis to the rack using the four #12-24 screws (included). On one side of the chassis, insert a wire management ring (includ- ed) between the chassis mounting bracket and the head of the screw, as shown below, and tighten the screws tight enough to hold the ring in place.
Cabling a System The MIX 56 chassis contains two independent systems that each require cabling. Telect recommends routing cables to the side of the chassis the system is on, not crossing the cables to the other side of the chassis.
Page 31
You need the following items to cable a system as a multiplexer with full DSX functionality: • 24 AWG cross-connect wire • Two 75 ohm coax cables with BNC connectors (Telect recommends 90-degree connectors, as shown below) • One RJ-45 Ethernet cable (shielded, groundable) •...

DSX O PERATION When a MIX 56 system is used as a DSX only, with DS1 signals connected to the rear 64-pin connectors, or as a multiplexer with DS1 signals connect- ed to the front wire-wrap pins, you can perform all DSX functions includ- ing cross-connecting circuits with other network elements, rerouting traffic with patch cords, and nonintrusive monitoring signals.
MIX 56 User Manual To Patch with Two Single Patch Cords Step Action Insert a single patch cord into the IN jack of the first jack. Insert the other end into the OUT jack of the second jack. Insert another single patch cord into the OUT jack of the first jack.
ODEM PERATION You can connect a modem to the MIX 56 serial port to control the system remotely over an analog phone line. To do so, you must set the “Modem Detect” field on the System Interfaces screen to “Enabled” (Chapter 2) and install the modem according to the instructions in Chapter 2.
• Via Remote Control: If the MIX 56 is connected over the DS3 link to another MIX 56 and they are both in C-bit mode on the DS3 link, then a remote control ses- sion can be run where the user is controlling the MIX 56 at the remote end of the DS3 link.
8 data bits, 1 stop bit, no parity; and its baud rate must match the Craft port’s setting of the MIX 56. Craft port baud rate choices are 9600, 19200, 38400, 57600, or 115200. (The baud rate can be set from the Craft inter- face’s System Interfaces screen or the TL1 command “set-baud”.)
Configure the terminal or PC port for 8 data bits, 1 stop bit, and no parity. Configure the terminal for the same baud rate as the MIX 56 is set for in the System Interfaces screen. Choose between 9600 (default), 19200, 38400, 57600, or 115200 baud.

MIX 56 ONFIGURING Each MIX 56 chassis houses two independent systems. When you access the Craft interface, whether through an Ethernet port on the rear or a Craft port on the front, your settings and configurations pertain only to the sys- tem on the same side of the chassis as the port to which you connected.
