  • Page 30 Provisioning 152-388-115-03, Issue 03 HDSL2 BER (HBER) Option. The HBER option permits the monitoring of loop integrity and reporting of alarms when excessive errors are detected. The PM primitive used for this purpose is the CRC checksum performed on the HDSL2 frame for both directions of transmission. It is, therefore, called a block error rate rather than the bit error rate associated with the DS1 interface.
  • Page 31 152-388-115-03, Issue 03 Provisioning If an ESF is received from the CPE, it is passed to the network, and the network’s inbound framing is passed on to the CPE. • FCON: This is the forced conversion setting. Table 8 below lists the HiGain HDSL2 responses to both the ACON and FCON settings for the CONV option.

If the ESF RAI to SF RAI Overwrite (ROVR) option is enabled, a network ESF RAI or ESF RAI-CI pattern can be converted into a CPE SF RAI or SF RAI-CI pattern, and thus overwrite bit 2 of every DS0 channel with a zero.
  • Page 33 152-388-115-03, Issue 03 Provisioning Fractional T1 (FT1) Option. Fractional T1 circuits can be used in feeder networks to provide frame relay service. If such circuits are maintained by a DDS test group, then these circuits must respond to DDS/DS0 latching loopback commands which is the only tool test groups have at their disposal.
  • Page 34 Provisioning 152-388-115-03, Issue 03 The NLOC loopback is calleda tandem DS0 DP loopback. It is used to select one of many loopback points when there are several identical data ports in tandem. The NI loopback is assigned to the H2TU-R (NREM) since it is usually located at the Network Interface (NI).
