5.1.35 Interface Mapping

An Interface Mapping is a mapping between MTP2 and PCI interfaces.

Select the VSTP, and then Configuration, and then Interface Mapping page. The page displays the elements on the Interface Mapping View, Insert, and Edit pages.

Note:

Data Input Notes apply to the Insert and Edit pages only; the View page is read-only.

Table 5-35 Interface Mapping Elements

Element Description Data Input Notes
Board Type

This field defines the Type of Board.

Default = eLynx

Range = eLynx, ADAX
Channel Name

This is the name assigned to interface mapping.

[Default = n/a; Range = Valid names are strings between one and 32 characters, inclusive. Valid characters are alphanumeric and underscore. The name must contain at least one alpha and must not start with a digit.] [A value is required.]
Link Type

This defines the types of links which are added in VSTP.

[Default = n/a; Range = T1, E1, E1_hsl, T1_hsl] [A value is required.]
Speed

This defines the type of speed enums and their corresponding values.

[Default = n/a; Range = Lsl_56k, Lsl_64k, Hsl_2048k, Hsl_1536k] [A value is required.]
Host Name

The hostName is the name of the server associated with the interface mapping.

[Default = n/a; Range = Valid names are strings between one and 40 characters, inclusive. Valid characters are alphanumeric and hyphen. The name must start with one alphanumeric and must not start with a hyphen. ] [A value is required.]
Time Slot

This defines the time slot. Zero is not allowed value.

[Default = n/a; Range = 1-31]
Port

The defines the value of port assigned to interface mappping.

This is a mandatory field.

[Default = n/a; Range = 0-7]
Sequence Length

This defines the sequence bit length of the link.

[Default = n/a; Range = 7_BIT, 10_BIT, 12_BIT]
Encoding Scheme Indicator for use of B8ZS, HDB3 or AMI encoding/decoding .
Minimum Signal Unit Rate Minimum signal unit rate. The minimum number of SUs present on a link uniformly distributed.

Default = 1000

Range = 400-2000
2 Spare International Bits

Value of two Spare International bits of NFAS data.

[Default = 0; Range = 0-3]
5 Spare National Bits

Value of five Spare International bits of NFAS data.

[Default = 0; Range = 0-31]
Framing Indicator for framing format. Default: FRAMING_SF
CRC Defines if crc should be enabled or disabled. Default: Yes
T1 Cable Length

T1 cable length in feet between the nodes

[Default = 133; Range = 0-655]
Error Correction Method Error Correction Method. Default: BASIC
MSU Retransmission Threshold

Threshold of the number of MSUs available for retransmission. If the error correction method being used is PCR and this threshold is reached, no new MSUs or FISUs are sent. The retransmission cycle is continued up to the last MSU entered into the retransmission buffer in the order in which they were originally transmitted.

[Range = 1-1023]
MSU Octet Retransmission Threshold

Threshold of the number of MSU octets available for retransmission. If the error correction method being used is PCR, and this threshold is reached, no new MSUs or FISUs are sent. The retransmission cycle is continued up to the last MSU entered into the retransmission buffer in the order in which they were originally transmitted.

[Range = 300-287744]

You can perform add, edit, or delete tasks on VSTP>Configuration>Interface Mapping page.

Adding an Interface Mapping

Perform the following steps to configure a new Interface Mapping:

  1. Click Insert.

    Note:

    The new Interface Mapping must have a name that is unique across all Interface Mapping at the SOAM. In addition, the Interface Mapping's IP Port combination must also be unique across all Interface Mapping configured at the SOAM.
  2. Enter the applicable values.
  3. Click OK, Apply, or Cancel

Editing a Interface Mapping

Use this procedure to change the field values for a selected Interface Mapping. (The Interface Mapping Name field cannot be changed.):
  1. Select the Interface Mapping row to be edited.
  2. Click Edit
  3. Enter the updated values.
  4. Click OK, Apply, or Cancel

Deleting a Interface Mapping

Use the following procedure to delete a Interface Mapping.

Note:

You cannot delete a Interface Mapping if it is part of the configuration of one or more Linksets.
  1. Select the Interface Mapping to be deleted.
  2. Click Delete.
  3. Click OK or Cancel.
