WLAN Parameter

Sets the parameters related to WLI board interoperation and the parameters related to wireless terminal authentication.

Depending on the parameters, when they are changed the WBS24 wireless station they can be operated automatically again to reflect the changes. And, when System ID or System Key, etc. is changed, all the existing registered terminal information is initialized.

RF Channel

Sets the RF channels that the WBS24 uses. Up to six (6) channels can be specified and the default is three (3) (No.1, No.6, No.11).

Codec 1,2,3,4

Codec used for VoIP calls between the WBS24 and terminal.

Any of G.711u, G.711a, G.726, and G.729 can be specified.

Register VoWLAN

WLI Slot

Sets the location information of the cabinet and slot in which the WLI card is mounted.

Version

Parameter to view the version information of the WLAN module.

WLAN Switch

Option to support the WLAN switch. This option is applicable only if the AP TYPE is set to Commercial AP.

Max AP Channel

Used to restrict the number of channels for the Commercial AP.

This option is applicable only if the AP TYPE is set to Commercial AP.

Retransmission T1

When using an unreliable transmission protocol such as UDP, if there is no answer after transmitting a call, it is retransmitted. The RE-TRANS.T1 TIME is the first retransmission interval defined in the RFC2543.

Retransmission T2

Maximum retransmission interval defined in the RFC2543

Retransmission T4

This is defined and used for several uses in the RFC 2543. For example, in an unreliable transmission protocol, one of them is the time to wait after the USA (User Agent Server) receives an ACK message.

General Linger Timer

In an unreliable transmission protocol, the server cannot ensure that the client has received the last answer after it sent it.

In this case, until the retransmission that the server requested is received, it must retransmit the answer during this time. For example, it is the time to wait after sending a 200 OK message for an INFO message.

Invite Linger Timer

In an unreliable transmission protocol, the client cannot ensure whether the server has received the ACK message after the client sent an ACK for an INVITE Final Response. At this time, this is the time to wait after sending an ACK for the Final Response.
