Visual Network CSU/DSU's

NOTE:  there are about 20 models, which is difficult - luckily there are only several that we commonly use.  The text below is exactly what shows up in the pricing module with DOC for the two most common speeds :

56K CSU/DSU

VIS9 VNBDE-IB (R) 56K DSU W/INBAND

NOTE:  the (R) means "Rental"

T1 CSU/DSU

(USE THE 1-PORT INSTEAD OF 2-PORT BECAUSE IT IS MUCH LESS EXPENSIVE):

VIS9 VNCDE-1PIB (R) T1 1P DI INBAND W/ETHERNET

NOTE:  the (R) means "Rental"
