The following tables indicate which TMI (Traffic Modem Interface) cards and which RMI
(Redundant Modem Interface) cards should be used with each modem and data type:

Notes:
1) For CDM-600/L modem to switch data (Bal and Unbal) use a DB-15 to DB-15 data cable.
2) For CDM-625/A modem to switch data (Bal and Unbal) use a DB-9 to DB-15 data cable.
3) As of September 2008, the CRS-320 TMI is obsolete. Use the CRS-340 TMI in its place.
4) For CDM-625/A where the terrestrial data type is Ethernet, you can use only one of any
four Ethernet ports on the CDM-625/A rear panel in Ethernet Bridge Mode.
5) From Redundant Modem to RMI, use a DB-25 to DB-25 Control cable.
6) From Traffic Modem to TMI, use a DB-9 to HD-15 Control cable.
