Description
• The 25-pair cable connectors at the back panel
(see Figure 7 on
cross-connect terminal (Main Distribution Frame).
• The AUX port connects a Power Failure Transfer
Unit (PFTU) to the Media Gateway.
• The MG 1000T link ports connect the MG 1000T
Expansion to the MG 1000T Core. Port 1 and
Port 2 correspond with bulkhead connectors 1 and
2, shown in Figure 8 on
• The ELAN network interface connects the
MG 1000T Core SSC to the ELAN subnet. Port 2
is not used.
• The Attachment Unit Interface (AUI) is used with
earlier version SSC which require a Media Access
Unit (MAU).
• The SDI connector in the Media Gateway provides
an interface for a three-port SDI cable. The
three-port cable is used in an MG 1000T to break
out into TTY0, TTY1, and TTY2. For MG 1000E
this cable is not used unless a maintenance
access using TTY0 is desired.
• The DS-30X and CE-MUX cables connect the
Media Gateway to the Media Gateway Expander.
• DIP switches are available to set the ringing
voltages, ringing frequencies, and message
waiting voltages. See Figure 8 on
