248 Hardware Description and Reference for Avaya Communication Manager
TN2182C tone clock, tone detector, and call classifier (8
ports)
Note:
Note: This circuit pack is not used in a G650 Media Gateway.
The TN2182 tone clock integrates the following functions onto one circuit pack for all system
reliability configurations:
● tone generator
● tone detection-call classifier
● system clock
● synchronization
The TN2182 supports eight ports for tone detection and allows gain or loss applied to PCM
signals received from the bus. The TN2182 supports:
● stratum-4 enhanced clock accuracy
● MFC signaling, such as Russia MF
● Russia multifrequency shuttle register signaling (MFR)
● A- and Mu-Law companding
The TN2182CP performs the following functions:
● provides continuous cadenced and mixed tones
● allows administrable setting of tone frequency and level
● detects 2025-Hz, 2100-Hz, or 2225-Hz modem answerback tones
● provides normal and wide broadband dial-tone detection
In most configurations, the 2-circuit or 3-circuit pack combination can include either the tone
generator, tone detector, and call classifier. This combination can be replaced with this one
circuit pack to free one or two port slots.
Use the TN2182CP circuit pack with the TN429D analog line central office trunk for CAMA/E911
and incoming caller ID (ICLID). A TN2182 is required for main processor tone detection or for
additional tones to support CCRON, Russian ANI, and others.
