T200 HTU-R, Local Powered, 60 mA
Status Description
Off No sync between the HTU-C and HTU-R on loop 1/loop 2
Green Good signal quality on (4 to 9)
Yellow Marginal signal quality on (1 to 3)
Red Poor signal quality on (0)
Flashing Error detected on either end of loop 1/loop 2,
LED color represents loop signal quality, as shown above
Off DS1 signal is absent or is of a format that does not match the
provisioning of the HDSL circuit
Green DS1 signal is present and synchronized with the HTU-C
interface
Flashing Bipolar violation (BPV), frame bit error (SF mode) or CRC
error (ESF mode) detected
Off No alarm conditions exist
Yellow Remote alarm condition detected (HTU-C)
Red Local alarm condition (HTU-R) detected
Off Unframed mode
Green Unit is receiving SF data
Yellow Unit is receiving ESF data
Green T200 HTU-R LP is provisioned for AMI line coding
Yellow T200 HTU-R LP is provisioned for B8ZS line coding
Off Not in loopback or armed state
Green Active remote bidirectional loopback from the HTU-C toward
the customer and the network
Yellow Active local bidirectional loopback from the HTU-R toward
the customer and the network
2 Yellow Flashing Unit armed but not in a active loopback
