When LNW59, LNW82, or LNW504 VLF Main packs are installed, the LNW7 circuit packs are not supported. However, non-VLF Mains support the LNW7.
The DS1 low-speed interface transmits and receives a standard electrical DS1 signal as specified in GR-499-CORE (1.544 Mb/s nominal rate, DSX-1 interconnect specification). Line coding is provisionable per DS1 port to alternate mark inversion (AMI) or AMI with bipolar 8-zero substitution (B8ZS).
The E1 low-speed interface transmits and receives a standard electrical E1 signal as specified in ITU G.703, G.704, G.706, G.736, G.775, M.2100 (2.048 Mb/s nominal rate, DSX-1 interconnect specification).
The LNW7, LNW8, or LNW801 can be provisioned for the following DS1 formats: unframed (UF), superframe (SF), or extended superframe (ESF) as specified in GR-499-CORE, Section 10. In the case of SF or ESF format selections, DS1 performance monitoring information is collected by monitoring the associated DS1 framing format per ANSI T1.231-1997.
The following parameters are monitored on the DS1 interfaces:
The alarm level for the monitored parameters can be provisioned to critical (CR), major (MJ), minor (MN), not alarmed or status conditioned (NA), not reported (NR).
When transmitting DS1/E1 signals to a DSX panel, the maximum cable length is 655 feet.
The LNW7, LNW8, or LNW801 interfaces support the following loopbacks:
Line build-outs are software-provisionable. The maximum distance depends on the cable type. The maximum cable length for DX1 lines is 665 feet.
PM data is reported for DS1/E1 signals when Alcatel-Lucent 1665 DMX is equipped with the LNW7, LNW8, or LNW801 circuit packs.
For a detailed list of PM parameters and thresholds, see Performance monitoring.
