Chapter 8 Interface and Subinterface Management
POS Subinterface Management—Configuration Window
POS Tab
The following areas are available on the POS tab of the POS Sub-interface Management - Configuration
window:
•
POS Interface
•
Path Message (C2)
•
Path Message (J1)
POS Interface
The POS Interface area contains the following information:
•
CRC—Cyclical redundancy check (CRC) word size. The CRC is an error-checking technique that
uses a calculated numeric value to detect errors in transmitted data.
•
Payload Scrambling—Indicates whether or not SONET payload scrambling is enabled on the
interface. Payload scrambling ensures that there is sufficient bit-transition density to maintain the
transmit clock for synchronous signalling. Both ends of the connection must use the same
scrambling algorithm.
•
Encapsulation—Indicates whether HDLC or PPP encapsulation is used on the interface.
Path Message (C2)
The Path Message (C2) area contains the following information:
•
SONET Overhead C2 Byte—Value of the SONET overhead Path Signal Label (C2), which indicates
the contents of the SONET STS-SPE Higher Order VC. This attribute is read-only. These are
possible values:
–
207 (0xCF) = PPP or HDLC with no payload scrambling
–
22 (0x16) = PPP or HDLC with payload scrambling
Path Message (J1)
The Path Message (J1) area contains the following information:
•
Expected Size—Maximum length of the expected receive SONET Path overhead message in bytes.
•
Expected Label—The expected receive SONET Path overhead message. If the expected label is
longer than the expected size, it will be truncated.
•
Transmit Size—Maximum length of the transmitting SONET Path overhead message in bytes.
•
Transmit Label—Transmitting SONET Path overhead message. If the transmitting label is longer
than the transmitting size, it will be truncated.
•
Modify Path Message (J1) button—Launches the POS Sub-interface Management - Modify POS J1
window to modify the expected receive and transmit SONET Path overhead message.
