ou may use Call Filtering feature of the Ultra Switch 100 to screen the

incoming calls. When the Call Filter mode is enabled, only those calls with

correct access code can pass through the Ultra Switch 100 to their designated

destination.

here are three Call Filter modes: (1) Fax Filter mode, (2) Modem Filter

Mode, and (3) Phone Filter Mode. When working in the Fax Filter mode,

the Ultra Switch disables the feature of automatic fax switching and

processes fax switching completely through manual switching. In other

words, when detecting the incoming CNG tone, the Ultra Switch disconnects

the line immediately. All the incoming fax calls must be processed manually

by entering the Fax Access Code. Likewise, when operating in the Modem

Filter mode, the reverse modem detection is disabled and routing to the

modem port can only be conducted by entering the correct Modem Access

Code. When operating in the Phone Filter mode, the Ultra Switch will block

the incoming voice calls unless # followed by a Phone Access code (page 21)

is entered within a certain time interval ( the time taken for issuing rings with

the number of rings equivalent to "Rings to Phone"; default: 5 rings, page

18 ). The caller will first hear three short beeps indicating that the Ultra

Switch is in the Phone Filter mode, and then a long silence during this

waiting (for Phone Access Code) period. If the Phone Access Code is not

entered correctly within this time interval, the Ultra Switch will route the line

to the fax port or disconnect the line depending on the operating parameters

set in the Ultra Switch. If the code is entered incorrectly, the caller may

press # first to delete the previous erroneous code and then enter the

correct code (Fax Access Code, Modem Access Code, or Phone Access

Code) to make correction.
