Service Name

The name of the service. It is recommended that only alphanumeric characters be used.

Account Name

The user name that is used to authenticate the connection. This is provided by the ISP or remote system.

Password

Default = Blank

Enter the password that is used to authenticate the connection. This is provided by the ISP or remote system.

Telephone Number

Default = Blank

If the connection is to be made via ISDN enter the telephone number to be dialed. This is provided by the ISP or remote system.

Firewall Profile

Default = Internet01 if present, otherwise <None>

From the list box select the Firewall Profile that is used to allow/disallow protocols through this Service.

Encrypted Password

Default = Off When enabled the password is authenticated via CHAP (this must also be supported at the remote end). If disabled, PAP is used as the authentication method.

Default Route

Default = Off

When enabled this Service is the default route for data packets unless a blank IP Route has been defined in the system IP Routes. A green arrow appears to the left of the Service in the Configuration Tree. Only one Service can be the default route. If disabled, a route must be created under IP Route.

Incoming Password

Default = Blank Shown on WAN and Intranet services. Enter the password that will be used to authenticate the connection from the remote Control Unit. (If this field has appeared because you have created a Service and User of the same name, this is the password you entered in the User's Password field).

Minimum No of Channels

Default = 1. Range = 1 to 30.

Defines the number of channels used to connect for an outgoing connection. The initial channel must be established and stable, before further calls are made.

Maximum No of Channels

Default = 1. Range = 1 to 30.  

Defines the maximum number of channels to can be used. This field should contain a value equal to or greater than the Minimum Channels field.

Extra BW Threshold

Default = 50%. Range = 0 to 100%.

Defines the utilization threshold at which extra channels are connected. The value entered is a %. The % utilization is calculated over the total number of channels in use at any time, which may be one, two etc.

For example, if Minimum Channels set to 1, Maximum Channels set to 2 and Extra Bandwidth set to 50 - once 50% of first channel has been used the second channel is connected.

Reduce BW Threshold

Default = 10%. Range = 0 to 100%.

Defines the utilization threshold at which additional channels are disconnected. The value entered is a %. Additional calls are only dropped when the % utilization, calculated over the total number of channels in use, falls below the % value set for a time period defined by the Service-Idle Time. The last call (calls - if Minimum Calls is greater than 1) to the Service is only dropped if the % utilization falls to 0, for a time period defined by the Service-Idle Time. Only used when 2 or more channels are set above.

For example, if Minimum Channels set to 1, Maximum Channels set to 2 and Reduce Bandwidth is set to 10 - once the usage of the 2 channels drops to 10% the number of channels used is 1.

Callback Telephone Number

Default = Blank

The number that is given to the remote service, via BAP, which the remote Control Unit then dials to allow the bandwidth to be increased. Incoming Call routing and RAS Services must be appropriately configured.

Idle Period (secs)

Default = 10 seconds. Range = 0 to 999999 seconds.

The time period, in seconds, required to expire after the line has gone idle. At this point the call is considered inactive and is completely closed.

For example, the 'Idle Period' is set to X seconds. X seconds before the 'Active Idle Period' timeouts the Control Unit checks the packets being transmitted/received, if there is nothing then at the end of the 'Active Idle Period' the session is closed & the line is dropped. If there are some packets being transmitted or received then the line stays up. After the 'Active Idle Period' has timed out the system performs the same check every X seconds, until there are no packets being transferred and the session is closed and the line dropped.

Active Idle Period (secs):

Default = 180 seconds. Range = 0 to 999999 seconds.

Sets the time period during which time the line has gone idle but there are still active sessions in progress (for example an FTP is in process, but not actually passing data at the moment). Only after this timeout will call be dropped.

For example, you are downloading a file from your PC and for some reason the other end has stopped responding, (the remote site may have a problem etc.) the line is idle, not down, no data is being transmitted/ received but the file download session is still active. After the set time period of being in this state the line will drop and the sessions close. You may receive a remote server timeout error on your PC in the Browser/FTP client you were using.

Minimum Call Time (secs):

Default = 60 seconds. Range = 0 to 999999 seconds.

Sets the minimum time that a call is held up after initial connection. This is useful if you pay a minimum call charge every time a call is made, no matter the actual length of the call. The minimum call time should be set to match that provided by the line provider.

Extra Bandwidth Mode

Default = Incoming Outgoing

Defines the mode of operation used to increases bandwidth to the initial call to the remote Service. The options are:

• Outgoing Only Bandwidth is added by making outgoing calls.

• Incoming Only Bandwidth is added by the remote service calling back on the BACP number (assuming that BACP is successfully negotiated).

• Outgoing Incoming Uses both methods but bandwidth is first added using outgoing calls.

• Incoming Outgoing Uses both methods but bandwidth is first added using incoming BACP calls.

IP Address

Default = 0.0.0.0 (address assigned by ISP)

An address should only be entered here if a specific IP address and mask have been provided by the Service Provider. Note that if the address is in a different domain from the system then NAT is automatically enabled

IP Mask

Default = 0.0.0.0 (use NAT)

Enter the IP Mask associated with the IP Address if an address is entered.

Primary Transfer IP Address

Default = 0.0.0.0 (No transfer)

This address acts as a primary address for incoming IP traffic. All incoming IP packets without a session are translated to this address. This would normally be set to the local mail or web server address.

For control units supporting a LAN1 and LAN2, the primary transfer address for each LAN can be set through the System Settings > System > LAN1 and System Settings > System > LAN2 tabs.

RIP Mode

Default = None

Routing Information Protocol (RIP) is a method by which network routers can exchange information about device locations and routes. RIP can be used within small networks to allow dynamic route configuration as opposed to static configuration using. The options are:

• None The LAN does not listen to or send RIP messages.

• Listen Only (Passive) Listen to RIP-1 and RIP-2 messages in order to learn RIP routes on the network.

• RIP1 Listen to RIP-1 and RIP-2 messages and send RIP-1 responses as a sub-network broadcast.

• RIP2 Broadcast (RIP1 Compatibility) Listen to RIP-1 and RIP-2 messages and send RIP-2 responses as a sub-network broadcast.

• RIP2 Multicast Listen to RIP-1 and RIP-2 messages and send RIP-2 responses to the RIP-2 multicast address.

Request DNS

Default = Off.

When selected, DNS information is obtained from the service provider.  To use this, the DNS Server addresses set in the system configuration (System | DNS) should be blank. The PC making the DNS request should have the system set as its DNS Server. For DHCP clients the system will provide its own address as the DNS server.

Forward Multicast Messages

Default = On.

By default this option is on. Multicasting allows WAN bandwidth to be maximized through the reduction of traffic that needs to be passed between sites.

Auto Connect Interval (mins):

Default = 0 (disabled). Range = 0 to 99999 minutes.

This field defines how often this Service will automatically be called ("polled"). For example setting 60 means the system will call this Service every hour in the absence of any normally generated call (this timer is reset for every call; therefore if the service is already connected, then no additional calls are made). This is ideal for SMTP Mail polling from Internet Service Providers.

Auto Connect Time Profile

Default = <None>

Allows the selection of any configured Time Profiles. The selected profile controls the time period during which automatic connections to the service are made. It does NOT mean that connection to that service is barred outside of these hours.  For example, if a time profile called "Working Hours" is selected, where the profile is defined to be 9:00AM to 6:00PM Monday to Friday, then automatic connection to the service will not be made unless its within the defined profile. If there is an existing connection to the service at 9:00AM, then the connection will continue. If there is no connection, then an automatic connection will be made at 9:00AM.

Quota Time (mins)

Default = 240 minutes. Range = 0 to 99999 minutes.

Defines the number of minutes used in the quota. When the quota time is used up no further data can be passed to this service. This feature is useful to stop things like an internet game keeping a call to your ISP open for a long period.

Quota:

Default = Daily. Range = None, Daily, Weekly or Monthly

Sets the period during which the quota is applied. For example, if the Quota Time is 60 minutes and the Quota is set to Daily, then the maximum total connect time during any day is 60 minutes. Any time beyond this will cause the system to close the service and prevent any further calls to this service. To disable quotas select None and set a Quota Time of zero.

Chap Challenge Interval (secs)

Default = 0 (disabled). Range = 0 to 99999 seconds. The period between CHAP challenges. Blank or 0 disables repeated challenges.

Bi-Directional Chap

Default =Off.

Header Compression

Default = None selected

Enables the negotiation and use of IP Header Compression. Supported modes are IPHC and VJ. IPHC should be used on WAN links.

PPP Compression Mode

Default = MPPC

Enables the negotiate and use of compression. Do not use on VoIP WAN links. The options are:

• Disable Do not use or attempt to use compression.

• StacLZS Attempt to use STAC compression (Mode 3, sequence check mode).

• MPPC Attempt to use MPPC compression. Useful for NT Servers.

PPP Callback Mode

Default = Disabled.

The options are:

• Disable Callback is not enabled

• LCP (Link Control Protocol) After authentication the incoming call is dropped and an outgoing call to the number configured in the Service is made to re-establish the link.

• Callback CP (Microsoft's Callback Control Protocol) After acceptance from both ends the incoming call is dropped and an outgoing call to the number configured in the Service is made to re-establish the link.

• Extended CBCP (Extended Callback Control Protocol) Similar to Callback CP except the Microsoft application at the remote end prompts for a telephone number. An outgoing call is then made to that number to re-establish the link.

PPP Access Mode

Default = Digital64

Sets the protocol, line speed and connection request type used when making outgoing calls. Incoming calls are automatically handled (see RAS services). The options are:

• Digital64 Protocol set to Sync PPP, rate 64000 bps, call presented to local exchange as a "Data Call".

• Digital56 As above but rate 56000 bps.

• Voice56 As above but call is presented to local exchange as a "Voice Call".

• V120 Protocol set to Async PPP, rate V.120, call presented to local exchange as a "Data Call". This mode runs at up to 64K per channel but has a higher Protocol overhead than pure 64K operation. Used for some bulletin board systems as it allows the destination end to run at a different asynchronous speed to the calling end.

• V110 Protocol is set to Async PPP, rate V.110. This runs at 9600 bps, call is presented to local exchange as a "Data Call". It is ideal for some bulletin boards.

• Modem Allows Asynchronous PPP to run over an auto-adapting Modem to a service provider (requires a Modem2 card in the main unit)

Data Pkt. Size

Default = 0. Range = 0 to 2048.

Sets the size limit for the Maximum Transmissible Unit.

BACP

Default = Off.

Enables the negotiation and use of BACP/BCP protocols. These are used to control the addition of B channels to increase bandwidth.

Incoming traffic does not keep link up

Default = On.

When enabled, the link is not kept up for incoming traffic only.

Multilink/QoS

Default = Off.

Enables the negotiation and use of Multilink protocol (MPPC) on links into this Service. Multilink must be enabled if there is more than one channel that is allowed to be Bundled/Multilinked to this RAS Service.

In Fallback

Default = Off.

This option indicates whether the Service is in Fallback or not. A service can be set into fallback using this setting. Alternatively a service can be set into fallback using a time profile or short codes.

Time profile

Default = <None> (No automatic fallback)

Select the time profile you wish to use for the service. The time profile should be set up for the hours that you wish this service to be operational, out of these hours the Fallback Service is used.

Fallback Service

Default = <None>

Select the service that is used when this service is in fallback.
