I have had good luck with I've ordered over 20 items from them over the past couple of years and have had good luck every time. Prices almost always beat the big box stores and shipping is fast. My PA271W-BK-SV monitors came from PC-Canada and we saved over $400 on those alone. I buy all my Epson 3880 ink from them too. Tried a couple times since their shipping was free, but they never delivered either of my orders. Totally useless, but PC-Canada has been quite good. Darren Scala

The Cisco ONS 15454 SONET 56-port DS-1/E1 Card provides 56 DS-1 interfaces operating at 1.544 Mbps received over 100-ohm nominal twisted-pair cable or 56 E1 interfaces operating at 2.048 Mbps over 120-ohm nominal twisted-pair cable. The DS-1 and E1 interfaces are used for terminating transport signals within a central office or customer premises.

This card supports manual-mode or auto-mode frame-format provisioning, simplifying the activation of services. The DS-1s support asynchronous and byte-synchronous options for the mapping to VT-1.5. The E1s supports asynchronous mapping to VC-12 SDH.
