Configuring the Ultra-WAN CSU/DSU Interfaces 59 Configuring a CSU/DSU Interface for Single Path, Unstructured Service This section describes how to configure Ultra-WAN CSU/DSU interface for single path, unstructured service. To configure the Ultra-WAN CSU/DSU interface, follow these steps: 1 Set the FrameMode as appropriate for your setup: SETDefault ! -PAth FrameMode = T1_SF | T1_ESF | E1_CRC4 | E1_NOCRC where = 4A, 4B, 4C, or 4D. The FrameMode parameter allows you to specify the frame mode. The allowable values are the following: T1_SF T1_ESF E1_CRC4 E1_NOCRC Superframe format T1. Extended Superframe format T1. CRC-active E1. E1 without an active CRC. 2 Set the connector type as appropriate for your setup using: SETDefault ! -PAth CONNector = E1_Unstructured |T1_Unstructured where = 4A, 4B, 4C, or 4D. 3 Set the LineEncoding as appropriate for your setup using: SETDefault ! -PAth LineENCoding = B8ZS | AMI | HDB3 where = 4A, 4B, 4C, or 4D. The LineENCoding parameter specifies the transmission encoding method for a serial line. The coding method you specify for the serial line must match the attached communication device. AMI or B8ZS should be used for T1 connectors and HDB3 should be used for E1 connectors. NRZ and NRZI are not valid options on Ultra-WAN interfaces. 4 Set the LineDistance as appropriate for your setup using: SETDefault ! -PAth LineDistance = LH1|LH2|LH3|LH4|SH1|SH2| SH3|SH4|SH5|SH7 The LineDistance parameter determines the supported long haul (LH) or short haul (SH) line distance. For T1 lines both long haul and short haul settings are supported. Further granularity is provided in units of dB for long haul, and in units of feet for short haul.
