MMI EXAMPLE - Adding another 8 Extensions

I want to add another 8 port extension card to my monarch

I am going to put the card in the 9th slot from the left in my main shelf, (its marked ports 64-71)

Only Insert the new card when the power to the monarch is switched off and you have taken anti static precautions

Now we need to tell the Monarch what we want the extension numbers to be.

If we are happy with the MMI changes, we need to save them to the Daughter memory card, other wise next time the power is switched off the monarch may "forget" our changes. There is a battery backup on the static ram where the customer database is held, but this is often faulty.

first I check what the MMI says those ports are set up as:-

type LEND 64 71

they are all spare - good.

now decide what extension directory number to give the ports ..

see what numbers are free in our numbering scheme with LSDN..
