SUGGESTED ORDERING CODES
UTA120 (alone) – The UTA120 uses both Voice and Data, and can access a
variety of the voice capabilities that make ISDN valuable. To use this value,
your must decide how to provision your line to get the best value from the
telephone company.
These are the voice options you should consider:
1. Basic Voice (Caller ID only) -- Code “S”, and see the ACO note just below.
2. Supplementary Services (Call Waiting, Hold, Conference, Transfer, and Drop).
You may opt for ordering “S” plus any or all of these services. – “P”, “Q”, “U”
Here is where things get complicated. On some switches, there is a feature
called CACH/EKTS. Using CACH/EKTS is better and easier, but is
sometimes more expensive. It is also sometimes unnecessary; you only
need CACH/EKTS if you want more than basic voice services. Bottom Line
– if it doesn’t cost anything more, get CACH/EKTS; and if it does, decide if
it’s worth it for you. In general, it is recommended that you get CACH/EKTS
if possible.
+
NOTE: If you cannot or do not get CACH/EKTS, it is important that you
order Additional Call Offering (ACO) feature. This allows the UTA120 to
allow a 128Kbps call to drop to 64Kbps for incoming voice calls. Of course,
if you do not want this feature, do not order it.
For the UTA120 alone , the recommended package for full usage is “V”;
however, “V” is usually the most expensive. It may or may not be
cheaper to order “S” and add the specific features you want.
AO/DI or PADs – Some equipment makes use of the D-Channel for low
bandwidth data transfers. If are going to use these devices, or you are
going to use a device that supports Always On/Dynamic ISDN (AO/DI),
you may want to provision the line with D-Channel X.25 Packet,
capabilities. – “P”, “Q”, “W”, “X”
“P” and “Q” also include supplementary services with most Telephone
Companies, so these features may not have to be provisioned
separately. The difference between “P” and “Q” is that “Q” has
CACH/EKTS provisioning. Again, you must decide if you want
CACH/EKTS, but it is recommended. Some Telephone companies are
now implementing codes “W” and “X”, which are the same as “U” and “V”
but with D-Channel X.25 Packet, designed for AO/DI devices.
