Programming Multiple Units Overview Programming Multiple Units Overview Programming Multiple Units Overview Up to seven (7) EL25s can be installed on a single telephone line. Each unit must have a "Unique Unit ID" number and the "Number of Units in Chain" assigned to it. Set the Unit ID Number and Number of Units in Chain: 2 The unit ID identifies each unit within a chain. Adding or removing EL25s will require the unit ID's to be re-entered. Factory Setting: Unit ID 1 and Number of Units in Chain 1. 1 Press Then 2 Unit ID Number (1-7), Then 3 Total Number of Units in Chain (1-7), Then Important: This must be performed for EACH unit in the Chain. Example: Unit ID "1" Unique Unit ID Sequencial Order Unit ID "2" Unit ID "3" Unit ID "7" Telco Entrance Box Demarcation Point Residence Number of Units in Chain "7" Important: EACH unit in the Chain must have the same "Rings Before Answer". 16 Factory Setting - 5 Rings EACH unit in the Chain must have the same "Alternate Prefix". 115 Factory Setting - Normal Verify Unit Number: 111 This allows you to verify a unit's number within a chain. When you perform this step, the unit will respond with the number of beeps corresponding to its unit ID number. Two beeps, for example, mean the unit is number 2 in the chain. Then Note: You cannot program a unit within a multi-unit chain from a local/remote DTMF phone (Touch-Tone) unless you know the unit's ID number. Therefore, you can only verify the unit number while programming from the unit's front keypad. * If you make an error during an entry, press the asterisk key ( ) to begin again. Page 9
