	Table 64 Description of the LEDs on the MIM-1G.SHDSL panel
	LED	Description
	LINK	OFF means no link is present; ON means a
		link is present.
	ACT	OFF means no data is being transmitted or
		received; blinking means data is being
		received or/and transmitted.
Interface Cable
	The MIM-1G.SHDSL module uses regular telephone cables for connection.
n	Telephone cables have been included in the standard shipment package of
	MIM-1G.SHDSL.
Connecting the Interface	You only need a telephone cable to connect one port on a G.SHDSL module to the
Cable	PSTN network.

M/MIM-1ASL
Introduction	By far, the following ATM modules are available for the routers:
	■ 1-port ATM (Asynchronous Transfer Mode) 155 Mbps multimode fiber
	interface module (MIM-1AMM)
	■ 1-port ATM 155 Mbps single-mode fiber interface module (MIM-1ASM)
	■ 1-port ATM 155 Mbps single-mode long-haul fiber interface module
	(MIM-1ASL)
	These ATM modules function in the system to provide ATM interfaces for routers,
	supporting:
	■ Two frame formats: SDH STM-1 and SONET OC-3;
	■ Scrambling in data transmission;
	■ Both line clock (when working as DTE interface), and internal clock (when
	working as DCE interface);
	■ Local cell loopback, local payload loopback, and remote loopback.
