MIM-1POS

Introduction

MIM-1POS represents the 1-port SDH/SONET interface module. It supports interface rates up to 155.52

Mbps (STM-1/OC-3).

The MIM-1POS can use the protocols such as PPP, Frame Relay and HDLC at the data link layer and IP at

the network layer. It allows direct transmission of packets over SONET/SDH. It supports:

• Four SFP types: multi-mode short-haul (1310 nm), single mode medium-haul (1310 nm), single mode

long-haul (1310 nm), and single-mode ultra-long haul (1550 nm).

• 155.52 Mbps fractional interface

Interface attributes

The following table shows the interface attributes of the MIM-1POS interface module. For more

information about the attributes of the optional SFP transceiver modules, see "100-Mbps SFP transceiver

module."

LED Descri

tion

LINK/ACT

• ON means carrier signal has been received.

• Flashing means data is being received or/and transmitted.

• OFF means no carrier signal has been received.

LP/AL

• ON means the interface is in a loopback.

• Flashing means an AIS, LFA, or RAI alarm signal is present.

• OFF means no loopback or alarm is present.

Note:

AIS = Alarm indication signal; LFA = loss of frame alignment; RAI = Remote alarm indication
