This connects the MERLIN Attendant with the Basic Telephone and
Modem Interface 2 (BTMI-2) on the MERLIN Plus system control unit.
If you use the MERLIN Attendant only for backup call handling or after
hours, you need only one Attendant unless call traffic is heavy, as shown in
Table 1-3. When call traffic is heavy, the number of MERLIN Attendants
required depends on the number of calls you receive during peak hours.
If you know how many calls you receive per hour during peak hours, use
Table 1-3 to estimate how many Attendants you need. If you don't know
how many calls you receive per hour, use Table 1-4 to estimate how many
MERLIN Attendants you need based on how many incoming lines your
business has. Contact your authorized AT&T representative to order and
install additional MERLIN Attendants.
