Part No. TEL–09949, Rev A June 2001 Page 20 of 34 Pre-Installation Information and Activities A group’s network management signaling is passed along a multi-drop bus in the backplane to each NC port. One slot of each group is the Bus Master slot (NC 1 for group 1, NC 2 for group 2, etc.). The group number is identified by the Bus Master slot number (e.g., Group 1 uses Bus 1 Master slot). For a group’s NC port to work, its Bus Master slot must be occupied. Figures 9 and 10 show this for each backplane.

Part No. TEL–09949, Rev A June 2001 Page 24 of 34 Pre-Installation Information and Activities If the application requires more NC slaves than the larger backplanes have groups, connect multiple backplanes in the enclosure using the 1-card backplane. When combining backplanes in an enclosure, one modem card slot is lost for each type of backplane that is used. For example, two 9-modem card backplanes in an enclosure occupy 19 slots.
Part No. TEL–09949, Rev A June 2001 Page 25 of 34 Pre-Installation Information and Activities There are two ways to determine your modem’s software revision number. From the modem front panel: 1) Press the appropriate front panel control key (from your location in the configuration menu structure) until the following (for example) appears: Data 9600 T/D? 2) Press until the Operating Status appears (for example): DTE 19.2 RELIABL 3) Press until the following appears: Display Modem ID 4) Press .
