Avaya 1603SW Betriebsanweisung

This section contains information on how to administer 1603SW-I SIP IP Deskphones to 
minimize registration time and maximize performance in a Virtual LAN (VLAN) environment. If 
your LAN environment does not include VLANs, set the system parameter L2Q to 2 (off) to 
ensure correct operation.

TCP_KEEP_ALIVE_
STATUS

1

Indicates whether TCP/IP keep-alive should be enabled 
at the system. Values are 0=TCP keep alive disabled, 
1=TCP keep alive enabled.

TCP_KEEP_ALIVE_TIME

60

This time interval is the time 1603SW-I SIP IP 
Deskphones will wait before sending out a TCP 
keep-alive message (TCP ACK message) to the far-end. 
The time is controlled by the system's TCP/IP stack. The 
timer is restarted after application level data (for example, 
a SIP message) is sent over the socket. When the 
system is idle, this keep-alive time expires and results in 
sending a TCP ACK (keep-alive) packet. Valid values are 
10-3600 (seconds).

TIMEFORMAT

0

Display time according to defined format in the top line 
and in the call log. Values are:
0=am/pm format
1=24h format

TLSDIR

" " (Null)

Path name for https downloads. Character string of 0 to 
127 characters representing a directory name or path to 
directory.

VLANSEP

1 

Enables or disables VLAN separation. Controls whether 
frames to/from the secondary Ethernet interface receive 
IEEE 802.1Q tagging treatment. The tagging treatment 
enables frames to be forwarded based on their tags in a 
manner separate from telephone frames. If tags are not 
changed, no tag-based forwarding is employed. Values 
are: 1=On/Enabled, 2= Off/Disabled. This parameter is 
used with several related parameters. For more 
information, see 

VLANTEST

60 

Number of seconds to wait for a DHCPOFFER when 
using a non-zero VLAN ID (1-3 ASCII digits, from “0” to 
“999”).

WAIT_FOR_
REGISTRATION_TIMER

32

Time in seconds the SIP application will wait for a register 
response message. If no message is received, 
registration is retried. Range is 4-3600 (seconds).
