ADTRAN 5045 system manual 10/100BaseT/TX Connections RJ-48C, Alarm Contacts Plug-In Terminal Block

Section 3 Engineering Guidelines TRACER 5045 System Manual

Table 5 contains the wiring diagram needed for connecting the TRACER 5045 RS-232 interface to a modem using the null modem adapter.

The null modem interface must route Carrier Detect (CD) on pin 8 directly from the modem. When using the RS-232 interface for modem control, the modem must source CD only when actually connected to a carrier.

PIN	NAME		PIN	NAME
2	TX	3		RX
3	RX	2		TX
4	RTS	5		CTS
5	CTS	4		RTS
6	DSR	20		DTR
7	GND	7		GND
8	CD	8		CD

10/100BaseT/TX Connections (RJ-48C)

The physical Ethernet interfaces are provided by four RJ-48C jacks that deliver 10/100BaseT/TX interfaces for LAN connectivity. Each port has a green LINK LED to indicate a valid link and an amber ACT LED that blinks with data activity on the interface.

PIN	NAME		DESCRIPTION
1	TX1		Transmit positive
2	TX2		Transmit negative
3	RX1		Receive positive
4,5	—		Unused
6	RX2		Receive negative
7, 8	—		Unused

Alarm Contacts (Plug-In Terminal Block)

Normally open (NO) and normally closed (NC) alarm contacts are provided on the rear panel of the TRACER 5045 system. In normal operation, the NC contact is electrically connected to the common contact (COM) and the NO contact is isolated. During an alarm condition, the NC contact becomes isolated and the NO is electrically connected to COM. This allows alarm conditions to be reported to external alarm monitoring systems.
