AT-VP504E FXS 72
SNTP Settings The Simple Network Time Protocol (SNTP)
1
enables the notion of time
(date, month, time) into the AT-VP504E FXS. It is especially required
when dealing with features such as the Caller ID.
SNTP is used to synchronize a SNTP client with a SNTP or NTP server
by using UDP as transport (see RFC 1769 for more details).
To enable the SNTP feature:
1. Locate the sntpEnable variable (under sntpGroup ).
This variable enables the SNTP feature.
2. Set the sntpEnable variable to 1=Enable.
snmpSystemService A value which indicates the set of services that
this entity may potentially offer. The value is a
sum. This sum initially takes the value zero.
Then, for each layer, L, in the range 1 through
7, that this node performs transactions for, 2
raised to (L - 1) is added to the sum. For
example, a node which performs only routing
functions would have a value of 4 (2
(3-1)
). In
contrast, a node which is a host offering
application services would have a value of 72
(2
(4-1)
+ 2
(7-1)
). Note that in the context of the
Internet suite of protocols, values should be
calculated accordingly:
layer functionality
1 physical (e.g., repeaters)
2 datalink/subnetwork (e.g., bridges)
3 internet (e.g., supports the IP)
4 end-to-end (e.g., supports the TCP)
7 applications (e.g., supports the SMTP)
For systems including OSI protocols, layers 5
and 6 may also be calculated.
Default Value:72
