Nevertheless the number ofdata interfaces depends on the number of VC-4v that each channel uses.1 Using the Multirate card, it is possible to equip up to 512 STM-4 interfaces (the Multirate card supportsup to 16 STM-4 interfaces per card)2 Using SDH Multirate card with CWDM SFPsIssue 1 Copyright – Refer to Page 2 Page 17 of 74
