Parameter
Description
Unframed
No framing is selected, no overhead is added, and the modem is with other manufacturers’
equipment when operating in a ‘standard’ configuration.
EDMAC
Comtech EF Data’s proprietary framing is added. The framing permits the bi-directional passing of
M&C and AUPC data between local and distant-end units.
EDMAC-2
6.3.2.6.1 (CONFIG: Framing Mode) EDMAC or EDMAC-2
EDMAC is backward compatible with the CDM-500, CDM-550/T, CDM-570/570L, and
CDM-600/L modems. EDMAC-2 is a reduced overhead version of EDMAC. While it is not
completely backward compatible with the modems mentioned here, it is backward compatible in
some modes (for example, in TPC BPSK modes and at rates above 2.048 Mbps).
When you select EDMAC or EDMAC-2, the modem displays the following submenu:
Framing mix: AUPC-Only
AUPC+EDMAC (◄ ►,ENTER)
When you enable EDMAC or EDMAC-2 framing, the modem automatically
enables AUPC but the specific EDMAC feature (passing M&C data from a local
to a distant-end unit) requires further configuration.
Use the
◄ ► arrow keys to select AUPC-Only or AUPC+EDMAC. Press ENTER.
Parameter
Description
AUPC-Only
(Default) None of the EDMAC features are available, even though framing is still
enabled.
AUPC+EDMAC
The system further prompts whether to select the modem as an EDMAC Master or an
EDMAC Slave.
