Configuring IP Parameters for CESoPSN Bundles on CTP150 Devices (CTPView)
The CTP software uses the IP parameters to create IP packets.
Default buffer settings for CESoPSN bundles on CTP150 devices are calculated as follows:
If the packet size is less than 3 ms of payload, set the buffers as follows:
Minimum buffer=8 ms
Maximum buffer=16 ms
Packet buffer set=12 ms
If the packet size is greater than 3 ms of payload, set the buffers as follows:
Minimum buffer=1 (packet time)
Maximum buffer=2 (packet time)
Packet buffer set=3 (packet time)
For example, if the packet size is 80 bytes with one channel in the bundle and signaling is off, one packet time is calculated as:
80/8=10 ms
Before you begin:
Log in to the CTPView software at least at the Net_Admin level.
Connect the CTPView server to the CTP device for which you want to configure bundles.
To configure IP parameters for CESoPSN bundles using CTPView:
- In the side pane, select Bundle > Configuration.
- Run your mouse over the Display and Select an Existing Bundle bar.
- In the table of bundles, select the bundle that you want to modify.
- Under Bundle Options, configure the parameters described in Table 1, and click Click to Submit Bundle AND Port Changes.
Field | Function | Your Action |
---|---|---|
Bundle Description |
Specifies identifying information about the bundle. |
Type a description for the bundle. |
State |
Specifies whether the bundle is active or disabled. |
Select DISABLED or ACTIVE. |
Remote Address |
Specifies the name and IP address of the remote CTP device. |
In the first field, select the CTP device. In the second field, select an interface on the CTP device. |
Packet Size |
Specifies the size of IP packets that are created from data received at the port. The CTP software calculates a default packet size based on the number of time slots configured, the type of interface (T1 or E1), and the type of signaling (CCS or CAS). We recommend that you use the default setting unless you require changes because of network performance. If you choose to change the signaling, use the following guidelines:
|
Enter a packet size. |
Service Type |
Specifies the ToS byte to be used in the IP headers of packets sent from the CTP device to the IP network. For a mapping of ToS byte values to DSCP classes and settings, see Providing QoS for CTP Bundles by Using Service Type Overview. You do not need to set the ToS value to the same value on local and remote bundles. |
Enter a number from 0 through 255. |
Time to Live |
Specifies the maximum number of router hops that a packet can traverse. The CTP device sets the TTL value in IP packets that it sends to the IP network. The IP network does not alter or optimize the packet routing based on the TTL setting. You do not need to set the same TTL value on local and remote ports. |
Enter a number from 0 through 255. |
Source UDP Port |
Specifies the source UDP port. The source UDP port is used as the circuit identifier; you must configure both circuit endpoints to use the same UDP port. The UDP port must be unique on the CTP device. You will not be able to activate a port if another port is using the same source UDP port number. |
Enter a number from 1 through 65535. |
Min Buffer |
Specifies the minimum buffer size. |
Enter the number of milliseconds. The number that you can enter varies depending on the type of interface and signaling. |
Max Buffer |
Specifies the maximum buffer size. We recommend that you use the default setting unless you require changes because of network performance. |
Enter the number of milliseconds. The number that you can enter varies depending on the type of interface and signaling. |
Buffer Set |
Specifies the buffer size when the circuit enters a running state. We recommend that you use the default setting unless you require changes because of network performance. |
Enter the number of milliseconds. The number that you can enter varies depending on the type of interface and signaling. |
Bundle Description |
Specifies identifying information about the bundle. |
Type a description for the bundle. |
Signal Disable |
Disables or enables signalling at the bundle level for T1/E1 ports. |
