• RJ-45 plugs (shielded or non-shielded, depending upon CAT5 cable used), up to
6 per chassis
• If daisy-chaining MTAS shelves, 8-wire CAT5 shielded cable for COMM
connections is required.
NOTE: For daisy-chain configurations, CAT5 shielded cable is required for COMM
connections and it must be properly grounded on both ends. Refer to Chapter 4 and
Appendix A for more details.
2.5 Ethernet Requirements
The MTAS requires assignment and configuration of a static IP address, subnetwork
mask, and gateway. This information must be obtained prior to the MTAS Activation and
Testing phase of the installation.
NOTE: To be visible to the configuring PC, the PC and master MTAS shelves must
share the same IP subnetwork.
2.6 Shelf Power Supply
The MTAS-192 shelf is powered by standard –48VDC Central Office (CO) battery.
Although the shelf can operate from a single power feed, dual connectors are provided
for A and B power feed redundancy.
Figure 14: Dual Connectors for Power Feed
The power supply breakers/fuses required are minimum 1/2 A to maximum 1A; these
are typically located in the Power Distribution Bay/Block/Center at the top of the
equipment rack.
NOTE: The MTAS-192 power feeds must be connected to an appropriate disconnect
device
2.7 Physical Requirements
The MTAS-192 shelf is adaptable to 19" and 23" racks using universal mounting
