When both ports on a VWIC-2MFT-G703 are configured with the clock source set to line, they must use the same clock source, or timing slips can occur. The VWIC-2MFT-G703 is a Cisco 2-port E1 multiflex trunk interface card with G.703 support.
G.703 support lets the card pass unstructured E1 traffic, and a CSU/DSU is integrated on the card. The same clock source rule applies to the VWIC-2MFT-T1, VWIC-2MFT-E1 and VWIC-2MFT-E1-DI cards.
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, the card connects only to intra-building or non-exposed wiring or cabling. The intrabuilding cable must be shielded, with the shield grounded at both ends.
The card is one of the VWICs supported in the NM-HDV2 network module. The 1-port card is the VWIC-1MFT-G703, and on the VWIC2-2MFT-G703 each port can be set to an independent clock source for data applications. More voice and WAN cards are in Cisco interface cards.
