21 28-Channel Framer Block Functional Description
21.2 Transport Applications
The transport application of the Super Mapper is depicted in
per interfaces with LIUs at the DS1/E1 rate in this mode. The data is either framed or unframed DS1s. In the trans-
mit path direction (Tx, to the mapper), the framer receives framed or unframed DS1/E1 data from its line interface
and sends this line data and clock (via the DS1 cross connect) to the mapper block. The framer can be provi-
sioned to frame align the data prior to sending it to the mapper section. The framer can be provisioned for perfor-
mance monitoring on the data and in ESF mode transmit PRMs back to its line interface.
In the receive path direction (Rx), the mapper sends the line data and clock (through the DS1 cross connect) to the
framer block. This data may be framed or unframed DS1/E1 data. The framer can be provisioned to frame align
the data and transmit a frame sync signal in addition to the data and clock. The framer can be provisioned for per-
formance monitoring on the data. In ESF mode, it can automatically generate and send PRMs back to the mapper
interface.
