The TN2182 is a combined Tone-Clock/Detector circuit pack, providing Tone-Clock functionality 
to a non IPSI PN. It provides 8 Enhanced Tone Receiver (ETR) ports. Each of these ports 
combines the individual capabilities of a DTMR-PT, a GPTD-PT, and a CLAS-PT. Thus, each 
TN2182 port offers any tone-detection function previously provided by a TN748, TN420, or 
TN744 Tone Detector board.
The TN2182 also provides either Mu-law or A-law tone detection.
Since the TN2182 also provides Tone-Clock function for non IPSI port networks, only one (or 
two if your system is duplicated) TN2182 circuit packs may reside in a PN. If more 
tone-detection resources are needed, the additional resources must be provided by TN748, 
TN420, or TN744 circuit packs.

A Tone Clock circuit resides on each IPSI board. For increased reliability, there is a duplicated 
server, one in active mode and one on standby. However, there is only one control network and 
one IPSI per port network as shown in 

. Therefore there is only one Tone Clock 

circuit per port network.
