8.8.1.7 Mapping E1 Channels onto a 1.544MHz Backplane
The user can use the RSCLKM bit (RIOCR.4) to enable the receive elastic store to operate with a 1.544MHz
backplane (24 channels / frame + F-bit). In this mode the user can choose which of the E1 time slots will be
ignored (not transmitted onto RSER) by programming the Receive Blank Channel Select registers
(RBCS1:RBCS4). A logic 1 in the associated bit location causes the elastic store to ignore the incoming E1 data for
that channel. Typically the user will want to program eight channels to be ignored. The default (power-up)
configuration will ignore channels 25 to 32, so that the first 24 E1 channels are mapped into the 24 channels of the
1.544MHz backplane. In this mode the F-bit location at RSER is always set to 1.
For example, if the user wants to ignore E1 time slots 0 (channel 1) and TS16 (channel 17), the
registers would be programmed as follows:
8.8.2 IBO Multiplexer
The Interleaved Bus Operation (IBO) multiplexer is used in conjunction with the IBO function located within each
framer/formatter block (controlled by the
simplifies user interface by connecting bus signals internally. The IBO multiplexer eliminates the need for ganged
external wiring and tri-state output drivers on the RSER and RSIG pins. This option provides a more controlled,
cleaner, and lower power mode of operation.
Note that the channel block signals TCHBLK and RCHBLK are output at the rate of the of IBO selection. Hence, a
4.096MHz IBO would have the channel blocks (if programmed active at the rate of 4.096MHz). The particular
blocking channel would be active for a duration of the channel if programmed.
The DS26524 also supports the traditional mode of IBO operation by allowing complete access to individual
framers, and tri-stating the RSER and RSIG pins at the appropriate times for external bus wiring. This mode of
operation is enabled per framer in the associated
disabled (IBOMS0 = 0 and IBOMS1 = 0).

the pin function changes for each mode of the IBO multiplexer.

Note: The addresses shown are for Framer 1. Addresses for Framers 2 to 4 can be calculated by using the following: Framer n = (Framer 1
address + (n - 1) x 200h), where n = 2 to 4 for Framers 2 to 4.
