Overview
Standard 1.0 Option 11 EC Installation and Maintenance Guide November 1999
Overview
Introduction
This chapter describes how to install the hardware that links
the EC 11 to the Meridian 1 Option 11 switch.
The EC 11 requires two interfaces to the Option 11 switch:
• one Application Module Link (AML) for signal and
control between the Enhanced MMP40 or MMP40 CPU
cards in the EC 11 and the NTAK02 SDI/DCH card in
the Option 11 switch
• one Network Loop Interface (NLI) for every 16 voice
channels between the Utility cards in the EC 11 and the
NTRB18AA MGate cards in the Option 11 switch
This chapter begins with a “quick start” overview of the AML
and NLI cabling and card configuration for a 2-node, 48-port
EC 11 connected to an Option 11 switch. The remainder of
the chapter explains details of various configurations.
