***If your system is configured with a 3/5 DS30 split, DS30 bus 7 is not available.

CTM switch settings

There are two models of CTMs.

CTM4: The CTM4 provides connections for four analog calling line identification (CLID) PSTN lines. Each voice line uses one line in the offset. Because each DS30 bus has four lines per offset, you can assign a maximum of four CTMs to a single DS30 bus by making the offset switch settings different for each MBM. You can also combine three CTMs with the trunk part of the 4x16 on the same DS30 bus.

CTM8: The CTM8 provides connections for eight analog calling line identification (CLID) PSTN lines. Each line uses one voice line. Because each DS30 bus has four lines per offset, you require two offsets. You can assign a maximum of two CTM8s to a DS30 bus by making the offset switch settings different for each MBM. You can also combine a CTM8 with a 4x16 on the same DS30 number. When you choose an offset number for the CTM8, the system automatically adds the next offset number. You cannot assign offset 3 to the CTM8 because this does not allow the MBM to assign the second set of lines.

You can also mix the two MBMs. For instance, if you have two existing CTM MBMs with offset 0 and 1, you can add a CTM8 on offset 2.
