This was my first experience with PC Canada, and I'm really impressed by the quality of their service. They called me to confirm my order and it took less than 48 hours to receive it. The price for my item was to lowest i've found on many similar websites.

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.
