Media Gateway profile (Part 3 of 3)

Property	Description
Connectors	• The 25-pair cable connectors at the back panel
(rear)	(see Figure 7 on page 52) provide access to the
	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 page 56.
	• 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	• DIP switches are available to set the ringing
	voltages, ringing frequencies, and message
	waiting voltages. See Figure 8 on page 56.
