Caution   Always wear an antistatic wristband when working on the system (especially when handling boards).

Caution    •   To ensure that the system operates without blocking, you must follow the instructions in Section 4.1.5.7 "Distribution of the PCM Highway" concerning PCM highway distribution.  •   For thermal reasons the IVMNL board may only be installed in the basic cabinet in a HiPath 3800 19-inch cabinet installation.  •   In order to avoid inactive IVM channels (due to the slow IVM board boot-up), the recommendations on Page 3-101 must be observed.

Caution   Always wear an antistatic wristband when working on the system (especially when handling boards).   Observe the measures for protecting electrostatically sensitive devices (see Section 1.2.6 "Notes").

If	Then
Board is to be removed.	Insert the tip of the board wrench marked "Pull" into the top opening on the front cover of the board to be removed.   Lever the board out of the shelf by pushing the board wrench upwards (Figure 4-16, left).   Then you can pull the module out of the system cabinet over the guide rails.
Board is to be added.	Using its guide rails slide the board into the system cabinet until it stops.   Insert the tip of the board wrench marked "Plug-In" into the bottom opening in the front cover of the board.   Lever the board into the shelf of the cabinet by pushing the board wrench upwards (Figure 4-16, right).

Step	Activity
1.	Rotate the board so that the backplane connector is pointing towards you.
2.	Carefully pull the locking hooks (Figure 4-23, A) on an adapter module apart.
3.	Align the adapter module on the connector strip (Figure 4-23, B) of the board. The outside edges of the adapter module must match the outside edges of the connector strip.
4.	Make sure that the outermost row of pins on the adapter module and the outermost row of jacks on the connector strip are aligned flush with one another and press the adapter module fully into the connector strip.
5.	Close the locking hooks.
6.	Repeat steps [2] to [5] to install the second adapter module.
7.	Plug the startup module (Figure 4-23, C,) into the hotplug connector on the board.

Restrictions for using the TMDID board   The TMDID board only uses the first half of a PCM segment. Consequently, a maximum of 64 channels is available on each PCM segment for TMDID-specific static time-division multiplex channels.   To guarantee that the system operates without blocking when using the TMDID, the boards on a PCM segment must not require more than the 64 static time-division multiplex channels.   Examples for a PCM segment:    •   2 x TMDID + 1 x DIU2U = 64 static time-division multiplex channels = approved equipment  •   1 x TMDID + 1 x TMC16 + 1 x DIU2U = 72 static time-division multiplex channels = unapproved equipment  •   1 x TMDID + 2 x SLMO2 = 8 static and 96 dynamic time-division multiplex channels = approved equipment

1A time-division multiplex channel is required if a call is being conducted over the "home SLCN board" of a mobile telephone. If a call is being conducted over a "Current location SLCN board", additional time-division multiplex channels will be required. More information is provided in Section 11.5 "Multi-SLC and System-Wide Networking". 2The maximum number of masters and slaves possible is taken into consideration. 3Static time-division multiplex channel assignment for operation as a trunk board, dynamic assignment for operation as a subscriber line module.

1The basic cabinet provides two PCM highway bundles with 2 x 4 PCM highways each. DIUT2, DIUN2, DIU2U (for U.S. only), and STMI2 use the PCM highways from trunk group F. Thus there are an additional 128 time-division multiplex channels available for these boards in the basic cabinet for slots 1 - 5 and slots 7 - 10. If HiPath 3800 is used as a two-cabinet system, the PCM highway trunk group F cannot be used.
