Cisco 56-port DS-1/E1 Interface Card
Cisco 56-port DS-1/E1 Interface Card
SKU: 11882451 MFR: Cisco Systems Inc
Product Description
Cisco 56-port DS-1/E1 Interface Card - 2.048
Manufacturer : Cisco Systems Inc
Manufacturer Part No : 15454-DS1E1-56
Product Details
Cisco ONS 15454 MSPP
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.
Features:
- Transmit ports can be retimed by the node clock or through-timed from the received client interface signal
- Allows a single card type to support either DS-1 or E1 signals (not at the same time)
- DS-1 and E1 ports can be selected as an input timing source for the network element
- Ports can be provisioned for asynchronous or byte-synchronous mapping to VT-1.5s
- DS-1 only: All 56 ports are configured for DS-1s (first 28 ports support retiming)
- E1 only: All 56 ports are configured for E1s (first 21 ports support retiming)
