This is done in two steps: • Selecting the network type according to which the system clock will synchronize. Only one system type may be selected for clocking. The clock source is then defined in the “system cfg”. • Selecting the spans of the selected network that will act as Master and Backup clocks.
3 System Architecture The MGC+ unit is designed to provide maximum reliability, minimum interruptions, and effortless maintenance. Removable active components are accessed via the front panel to provide quick and easy serviceability.

Chapter 4 - Hardware Description The MPI-4/8 Network Interface Module MPI is an acronym for the Multi Protocol Interface card. The MPI-8 is a serial communications interface card that uses certain protocols to communicate to endpoints, “Data Terminal Equipment” (DTE), or “Data Communications Equipment” (DCE). The protocols that it uses are RS-449, RS-530, V.35, and RS-366, which is a dialing protocol. The MPI-4/8 Network Interface Module is connected to the DCE (supplied by the customer) via the MPI box.
MGC+ Hardware and Installation Manual Each 160-pin connector can be connected to one 160-pin connector located on the front panel of the MPI box. 160-pin connector Converts data from four ports PORTS A 1-4 A PORTS 9-12 PORTS B 5-8 B PORTS 13-16 160-pin connector Converts data from four ports Figure 4-15: MPI box front panel Each of the 160-pin connectors on the MPI box interfaces to four serial ports found on the back of the MPI box.
Chapter 4 - Hardware Description MPI-4/8 Network Interface Data Stream When the MCU is set as a DTE The ISDN data stream flows from the ISDN telecommunication network through the DCE to the serial port (37-pin connector) on the MPI box. The data is then directed from the 37-PIN connector to the 160-PIN connector, which gathers data from four different ports, and channels the data stream to the 160-pin connector located on the MPI-4/8 front panel.
MGC+ Hardware and Installation Manual When the MCU is set as a DCE The serial data stream flows from the endpoint (DTE) through the serial connector entering the MPI box by way of the 37-pin connector. The data is then directed from the 37-pin connector to the 160-pin connector connected to the MCU (DCE). In the MCU the data stream is converted to a TDM format, and then sent to the backplane information bus. Since this is a full duplex communication, the data is also bi-directional.

MGC+ Hardware and Installation Manual • From a non-encrypted conference to an encrypted conference or another non-encrypted conference. When the ALLOW_ENCYPT_IN_PARTY_LEVEL flag is set to NO, the participant’s encryption setting must match the conference encryption setting’s to be moved to the other conference. For example, encrypted participants can only move from an encrypted conference to another encrypted enabled conference.
Chapter 4 - Hardware Description IP/SIP In the IP/SIP section of the Resources Report both non-encrypted and encrypted participants are grouped together. For example, if one encrypted and one non-encrypted participants using a line rate of 128 Kbps attend a conference, the resource report displays the sum of the used resources of both participants together. In this case the nonencrypted participant is allocated 1 port and the encrypted participant 2 ports, totalling 3 ports.

Appendix A: Interfaces Pin Assignment Cables For the MPI-4/8 Network Interface Module There are three new cables for interfacing with the MPI-4/8 Network Interface Module in DCE. The difference in the cables is that they have certain pins that are crossed. A-6 1. Part Number: CON2044A – Adapter RS-449 (BD37) to V.35 (female) crossed DCE. 2. Part Number: CON 2045A- Adapter RS-449/EIA530 Crossed DCE (DB37M/DB37F). 3. Part Number: CON2046A- Adapter RS-449/RS-449 Crossed DCE (DB37M/DB37F).
