High Density Remote POTS (HD R-POTS)

SKU: 0110-0244 Category:

The High Density Remote Plain Old Telephone Service (HD R-POTS) plug-in card is a 24-port, loop start subscriber termination card. With support for 24 subscribers per card, the HD R-POTS card dramatically increases the capability of the Tellabs 1000 HD CBA to support high-density applications.

Material Status

Production

  • TR-008 and GR-303 only
  • Call Message Waiting Indicator (CMWI)
  • Remote test access to metallic tip and ring
  • 1830W loop length resistance (including station)
  • 900 Ohm structural impedance
  • Forward disconnect
  • On-hook transmission (CLASS) capability
  • Twenty-four (24) 2-wire circuits

Ease of Operations

The HD R-POTS card has two LED indicators on the front panel. A green BUSY LED indicator, when lit, indicates that the HD R-POTS circuit is busy or is being tested and must not be removed from service. A flashing red FAIL LED indicates that there is illegal signalling on any one circuit. A red FAIL LED indicates that the unit has failed.

Mechanized Loop Testing

The HD R-POTS also supports multiple loop testing systems including Mechanized Loop Testing (MLT).

High Density Analog Voice

The HD R-POTS supports a loop length resistance of 1830 Ohms, ring cadence following, local ring trip, on-hook transmission between ring-bursts, and forward disconnect. The card supports Call Message Waiting Indicator (CMWI).
