shows the connections for up to 24 off-premises analog telephones.
Concentrations of analog line pairs are used at both buildings to minimize the
off-premises wiring required. At the MDF, jumpers must be connected between 1
row/connecting block in the white field and up to 3 rows/connecting blocks in the
purple field. At the station location, a WP-90929, List 1 Concentrator Cable is
used. There are 8 station appearances on each of the 3 fingers of the
concentrator cable.
