IP Telephone Programming
250 IPT Data Assignment
8-8 Strata CTX Programming - Part 2: CTX WinAdmin Programming 6/04
05 Station Terminal
Authentication Mode
Apply this parameter if you want to reserve a PDN for the IP Telephone connected
at the present time. When ’apply’ is set, terminal authentication by MAC address of
IPT is valid. So if other IPT which has the same PDN is connected the network,
CTX rejects the registration of this IPT because the MAC address of IPT is
different. When ’not apply’ is set, you can move the PDN from a IPT to another IPT
and another IPT can be connected to the CTX. When ’don’t care’ is set, terminal
authentication for this telephone is determined by Program 150-02.
The Terminal Authentication setting ’Apply or Not Apply’ in this program overrides
the Terminal Authentication any setting in Program 150-02. Refer to Table 8-1.
Possible values: Apply, NotApply or DontCare (default)
06 Station MAC Address Station Media Access Control (MAC) Address. This address is hard coded uniquely
in each IPT. The MAC will only display if the IPT is connected to the BIPU-M1A and
is operating properly.
Possible values: Up to 12 digits
07 Voice Packet
Configuration Table Index
Select the Voice Packet configuration table that should be assigned to this IPT
(The voice tables are configured in Program 152). When the G711 Audio Codec is
selected in 08 codec below, the default values in Program 152-01, Table 1 should
be used. When the G.729A codec is selected in 08 Audio Codec below, the default
values in Program 152-01 Table 2 should be used.
Important! When switching the IP telephone from the G.711 to the G.729 codec
(the first time), the CTX will automatically switch the Voice Packet
Table from Table 1 to Table 2.
Possible values: 1~128 (CTX100 and CTX670 Basic)
1~256 (CTX670 Exp.)
08 Audio Codec Select the audio codec that should be used in this IPT.
Possible values: G711(default) or G729A
IP telephones have two built-in codecs:
The G.711codec – provides the highest voice quality but uses the most network
bandwidth (about 115kbps per IPT when in use).
The G.729A codec – provides less voice quality but uses the least amount of
network bandwidth (about 29kbps per IPT when in use).
High traffic or low speed networks may require the IP Telephones to use G729A.
Example
If installing remote IP telephones connected to Cable or DSL lines, the upstream
rate is usually restricted and may not provide a consistent upstream bandwidth
(advertised as 128kbs but is normally less because of traffic) so the G729a codec
would probably be the best choice for this situation.
The Voice Packet Table 'Program 250-07' and the VP Table's Voice packet
parameters 'Prg152' must be set properly for the codec assigned.
09 Display Software
Version Number of IPT
This is read-only. If any problem occurs, it is useful to analyze the problem with this
version. The sample of software version is “DIP11NA.” DIP1 represents the IPT
model. 1NA represents software version of IPT. “1N” represents the version of
updatable software and “A” means the version of not-updatable software
(BootROM).
