MPS 1000 System Hardware Overview
Figure 10: MDM Front View
For example, the MDM can provide 8 channels of FAX for a total of 16 channels per TMS.
Configuration of resources and protocols is covered in
Ethernet LAN Interface
The TMS interfaces with the system LAN by dual redundant Ethernets using TCP/IP. The chassis
Ethernets (designated A and B) are connected through the VRC backplane to separate hubs on the
chassis Network Interface Controller (NIC) or Hub-NIC.
Computer Telephony Bus Clocking
Voice and audio data is transmitted throughout the MPS 1000 over a synchronized Computer
Telephony (CT) bus system.
Figure 11: CT bus System Schematic
Dual redundancy for the CT bus is provided externally to the TMS. Conversation bridging across
multiple chassis is over a fiber optic link, (155Mb, ATM layer 1) provided (optionally) by the NIC
2000. This type of bridging is limited to a two-chassis environment. Systems larger than two VRCs
require the addition of one or more external Asynchronous Transfer Mode (ATM) switches. Dual-
Redundant systems need two external ATM switches.
Any DCC on the node can be configured as the source of either REFCLK_A or REFCLK_B. The
local reference oscillator on any TMS can be used for either reference clock.
