0,4831-20SYMPTOM:
- .
RESOLLITiON:PROCEDURE:In certain site specific environments (a quiet office or a quiet CO line), background
noise from the environment may be interpreted as noise on the 
tail. Not all locations
are affected by this noise. This condition may appear as low level clipping of the
voice and is caused by the zero 
c;oss overcircuit in the codec IC used on all CO
lines. This 
sit.uationaro_se_as a result of a revision change to the codec IC used an
all CO lines by the manufacturer of the IC. VCS has corrected this in production and
repair; however you may find locations where the condition is present and it can be
annoying to the customer.
If the CO codec (coder/decoder) 
C’s are of a certain revision, susceptibility to this
problem may be 
heIghtened. The soiution is to utilize two soeciiic versions of a
Texas Instruments 3054 type codec.
To determine the codec types:
Use the attached diagrams 
to locate the CO line codec G’s on each board type.
Each codec has a part number and manufacturer information silkscreened on top
of it.Acceptable 
codec(s):Pan Number:
TP3054ANMfg. 
infoAnyPart Number:
Mfg. Info:
TP3054BN
AMAAAAXNThe X must equai letters D-G in the manufacture information line to be the proper
revision. The X 
wiil aiways be the next to last digit on the manufacture line regardless
of the length of the line.
If you find a suspect codec 
IC and your customer is experiencing these symptoms,
the unit should be replaced with a non-suspect unit. Your suspect unit can be
upgraded using standard Vodavi 
MRA procedures.
