* Omit this value, if all cards are interconnected or none is connected.
* If unsure, don't give this parameter.
*
- * dslot:
- * NOTE: only one dslot value must be given for every card.
- * Also this value must be given for non-E1 cards. If omitted, the E1
- * card has D-channel on time slot 16, which is default.
- * If 1..15 or 17..31, an alternate time slot is used for D-channel.
- * In this case, the application must be able to handle this.
- * If -1 is given, the D-channel is disabled and all 31 slots can be used
- * for B-channel. (only for specific applications)
+ * dmask and bmask:
+ * NOTE: One dmask value must be given for every HFC-E1 card.
+ * If omitted, the E1 card has D-channel on time slot 16, which is default.
+ * dmask is a 32 bit mask. The bit must be set for an alternate time slot.
+ * If multiple bits are set, multiple virtual card fragments are created.
+ * For each bit set, a bmask value must be given. Each bit on the bmask
+ * value stands for a B-channel. The bmask may not overlap with dmask or
+ * with other bmask values for that card.
+ * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000
+ * This will create one fragment with D-channel on slot 1 with
+ * B-channels on slots 2..15, and a second fragment with D-channel
+ * on slot 17 with B-channels on slot 18..31. Slot 16 is unused.
+ * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will
+ * not function.
+ * Example: dmask=0x00000001 bmask=0xfffffffe
+ * This will create a port with all 31 usable timeslots as
+ * B-channels.
+ * If no bits are set on bmask, no B-channel is created for that fragment.
+ * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask)
+ * This will create 31 ports with one D-channel only.
* If you don't know how to use it, you don't need it!
