Entering alphanumeric characters
You enter names for extensions, departments, branch IDs, CO lines, and guest mailboxes by pressing the
dial pad key that corresponds to the character to be entered. The key’s possible entries will change each time
the key is pressed, and the display will show this. When the desired character appears on the display, press # to
confirm; the cursor will move to the next character position. You may move the cursor left (to correct an entry) by
pressing the left scroll key (

) or move right (to add a space) by pressing the right scroll key (

).

Selectable numbering plan
The ESI-50L’s selectable numbering plan offers three preconfigured three-digit plans. When an extension range
is selected, department numbers and guest mailbox numbers are also changed. However, regardless of which
extension range is selected, feature key codes, and CO line group access numbers will stay the same. The dial
plan range is selected through Installer programming Function 169 (see page D.9 for more information).
Note: The ESI Presence Management RFID Reader

uses one digital extension, regardless of dial plan..
