EMS Technologies Canada Ltd. HSD-400 Manuale Utente

To use the SBB service, the HSD-400 terminal obtains subscriber information from two SIM 
cards installed in the SCM. Each SIM card slot in the SCM is associated with a specific channel 
card—the slot next to the SCM connector is for channel card one, the third slot is for channel 
card two.

The HSD-400 terminal has three different ports that support the following interfaces: EURO 
ISDN S/T, serial (RS-232), and Ethernet (10BASE-T). Although able to support multiple 
configurations depending on user needs, the following constraints apply:

•

EURO ISDN S/T port supports Swift64 Mobile ISDN (circuit-switched) only

•

RS-232 port supports MPDS only

•

10BASE-T port supports Swift64 Mobile ISDN, SBB, and MPDS 

Only one service type can be used at one time-per HSD-400 terminal channel. 

For information about using the HSD-400 terminal in various cabin network configurations, 
refer to the eNfusion® HSD High-speed Data Terminal Developer’s Guide (MN-1252-13005).

Table 1-1 lists the physical characteristics and equipment specifications for the HSD-400 
terminal.
