TN2182 Tone-Clock Circuit Pack (for Non-IPSI
Connected PNs)
A TN2182 is a combined Tone Generator/Tone Detector board. It provides eight
Enhanced Tone receiver (ETR) ports. Each of these ports provides the functions
previously found individually on DTMR-PTs, GPTD-PTs and CLAS-PTs ports.
Each port on the TN2182 may be used for any tone-detection function that was
previously done by TN748, TN420, or TN744 Tone Detection boards.
The TN2182 provides Mu-law or A-law tone-detection capability.
Since the TN2182 also provides Tone-Clock function, only one TN2182 circuit
pack may reside in an PN (or two if your system is duplicated). If more
tone-detection resources are needed, the additional resources must be provided
by TN748, TN420, or TN744 circuit packs.
Error Log Entries and Test to Clear Values
Notes:
a. There are two possible alarm levels for this error type: major alarm and
minor alarm. These alarm levels are dependent on the administered
thresholds for TTR, CPTR, and CCTR. Each ETR port is capable of
operating an any of these.
A major alarm is raised if the total number of ports capable of TTR, CPTR
or CCTR detection currently in service is less than or equal to one-half of
the administered TTR, CPTR, or CCTR threshold number. Otherwise, a
minor alarm is raised. In either case, run the short test sequence against
the port (ETR-PT) and follow the error code procedures for the individual
tests.
