3 On the mapping list, locate the removed unit indicated as Units are not present.
4 Delete the old CAN Bus unit from the CAN Bus unit mapping list by entering: can remove_mapping <X>.
<X> identifies the old unit name and is digit between 0 and 3.
Step example: can remove_mapping dpm 2.
5 Add the new CAN Bus unit to the CAN Bus unit mapping list by entering: add_mapping dpm<X><track
ID>.
<track ID> is a Track ID of the new unit.
<X> identifies the new unit name and is a digit between 0 and 3.
Step example: can add_mapping dpm 2 JTH0500102
6 View the updated mapping list by entering: can check_mapping.
7 On the mapping list, check that there are no units labeled as Track ID not mapped or Units are not
present.

Cavity Combiner

Note: MTS 2 does not support Cavity Combiners.
There are two types of Cavity Combiners available:
• Auto Tune Cavity Combiners (ATCC)
• Manual Tune Cavity Combiners (MTCC)
MTCCs are functionally the same as ATCCs except that they are tuned manually instead of electronically.
Minimum channel spacing of the TX channels is 150 kHz while the recommended channel spacing is 250 kHz. This
limitation applies to all Cavity Combiners in all cabinets connected to the same transmit antenna.

Note: The new unit Track ID is present on the replaced unit label and indicated as Track ID not
mapped.
Note: 260 MHz configurations does not support MTCC.
