Table 1-1. Modem Port Status LEDs

LED	Description
CD	CD (Data Carrier Detect) LED is green and ON when carrier has
	been detected by the corresponding modem. There are 32 CD
	LEDs, one LED per channel, on the front of the Remote Annex
	6300.
TX/RX	TX/RX LED is green and flashes to indicate the corresponding
	modem is transmitting or receiving data. There are 32 TX/RX
	LEDs, one LED per channel, on the front of the Remote Annex
	6300. For North American models, up to 32 modems can be
	installed (although only 23 are active at any given time). For
	European countries that use E1 lines for PRI access, a maximum
	of 32 modems can be installed (only 30 are active at any given
	time).

The Modem Config Status LEDs indicate the number of modems installed. An LED is green if all the modems in its group are good. An LED is amber if one or more modems in its group are bad.

The PRI Channel Status LEDs indicate B channel allocation. There are 32 PRI Channel Status LEDs on the front of the Remote Annex 6300. For T1, 23 are used to indicate B channel allocation. For E1, 30 are used for B channel allocation.
