DS1 Port Switch To Protect ?

[menzelbob]

Simple question, can you switch just one port of the DS1-14, to the protect, or do you have to switch all the circits on the card to protect. Is the protection at the card level, or the port level ?

Thanks,

Bob

It might be right, please check with the below link. 1:N protection allows a single card to protect up to five working cards of the same speed, DS-1 or DS-3. A DS1N-14 card protects DS1-14 cards, a DS3N-12 card protects DS3-12 cards, and DS3N-12E cards protect DS3-12E cards. The standard DS1-14, DS3-12, and DS3-12E cards provide 1:1 protection only. 1:N protection operates only at the DS-1 and DS-3 levels. 1:N cards have added circuitry to act as the protect card in a 1:N protection group. Otherwise, the card is identical to the standard card and can serve as a normal working card .
