SLM-3650 Satellite Modem
Operation

SDM-100 Emulation Operation
The SDM-100 Emulation feature of the modem provides remote protocol compatibility
with existing SDM-100 modems, which makes several applications possible:
•
Add an SLM-3650 to a rack of SDM-100s with a protection switch.
•
Replace an SDM-100 requiring service with SLM-3650.
•
Use SLM-3650 as the backup modem for a rack containing a mix of SDM-100
and SLM-3650 modems.
SDM-100 Emulation is typically a closed network application, with no added overhead.
The modem does not require any additional hardware to operate in SDM-100 Emulation.
The basic modem configuration, which includes the 25-pin D Data I/O connector,
supports V.35, EIA-422, and EIA-232-C data.
Refer to Table 3-10 for SDM-100 emulation parameter settings.
