3.5.6 VLAN Configuration
3300IP-TRM phone implement QoS based on 802.1p, The QoS is used to mark the
network communication priority in the data link/MAC sub-layer. 3300IP-TRM will sort the
packets using the QoS and sends it to the destination.
VLAN Enable:
If enable the VLAN service, the second layer will realize separate
voice, signal and data transmission. To realize separate voice and data transmission by
dispose for IP precedence of ToS area of voice transmission. To reach upper layer switch
or router have priority to transfer voice transmission. (The prerequisite is the upper layer
switch or router has to identify ToS area.)
VLAN ID:
Dispose VLAN ID is add a Tag header after realize enable the VLAN
function. The realized voice packets transfer at the same VLAN. The prerequisite is it must
the same as VLAN of upper switch. The value range are 1~4094.
DiffServ Enable:
If enable the VLAN service, it indicates use DSCP mode to realize
three layers QoS. This moment, the DSCP of SIP signals which between 3300IP-TRM
Phone and MGC. It will use Class Selector 5 (The value is 0xA0). And the DSCP of
mediums information (In RTP packets) would be used the values of DiffServ Value field.
DiffServ Value:
The value range
:
0x28,0x30,0x38,0x48,0x50,0x58,0x68,0x70,0x78,0x88,0x90,0x98,0xb8.default is
0xb8 ,oxb8 stands for best fast transmission; 28-38 is guarantee for the transmission
priority for the 1st rank , 48-58 is guarantee for the transmission priority for the 2nd rank,
68-78 is guarantee for the transmission priority for the 3rd rank, 88-98 is guarantee for the
transmission priority for the 4th rank.

Digit map is a set of rules to determine when the user has finished dialing.
