on page 2 the asm code starts as follows:

/**********************************************************************/
/* DSMux.c This program uses a 8051-type microcontroller to interface */
/* with a multiplexed-bus RTC such as a DS12887, DS1687 or DS17887. */
/* This is an example program only and is not supported by Dallas */
/* Semiconductor Maxim */
/* Revision 1.0 2/19/03 */
/**********************************************************************/


my guess is then that it is also applicable to DS17887.

need I say more? (no I can't give you the actual code, as I am still learning and fairly new to 8051 environment...)

happy reading...
