The Cisco® ONS 15454 SONET 56-port DS-1/E1 Card provides a cost-effective, high-density DS-1/E1 interface solution for hand-offs and aggregation of large numbers of DS-1 and E1 circuits between networks. The card's high-density design frees up shelf-assembly slots for additional service-interface types.

Product Overview

The Cisco ONS 15454 SONET 56-port DS-1/E1 Card (Figure 1) 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.

Figure 1

Cisco ONS 15454 56-Port DS-1/E1 Electrical Interface

The 56-port DS-1/E1 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. The following port usage options are available:

• 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)

The DS-1/E1 signals are terminated on one of the Cisco ONS 15454 shelf assembly's high-density universal backplane interface connector (UBIC) electrical interface adapter (EIA) panels.

The 56-port DS-1/E1 card is provisionable for either transport over SONET or SDH payloads. When provisioned in SONET-mapping mode, the output payload are STS-1s whereby the DS-1s are mapped to VT-1.5 payloads (following Telcordia Technologies GR-253-CORE or Cisco mapping structures). Provisioned in SDH-mapping mode, the output is an STS-3/VC-4 whereby the E1s are mapped to VC-12 containers. The output STS-1 or STS-3c/AU-4 payloads are connected to the Cisco ONS 15454 system's cross-connect matrix, allowing the signal to be groomed with other services for transport over a SONET network. The E1 to AU-4 payload mapping structure allows interoperability with a payload generated by a 42-port E1 card on the Cisco ONS 15454 ETSI/SDH platform (Figure 3).

The first 21 E1 or 28 DS-1 ports can be provisioned for retiming. Retiming a port means the transmit DS-1/E1 clock is retimed to the clock reference of the network element (Cisco ONS 15454), removing the asynchronous relationship between the electrical line and SONET transport domains. When retiming is not selected, the DS-1/E1 transmission is through-timed, allowing the timing domains to be separate between the SONET and electrical signal. All DS-1 and E1 ports are provisionable to be used as a source of node timing, except when already provisioned in retiming mode or looped back.

The 56-port DS-1/E1 cards are deployable in six multiservice interface card slots (1, 2, 3, 15, 16, and 17) of the Cisco ONS 15454 Multiservice Provisioning Platform (MSSP) high-density shelf assembly (SA-HD). Printed on the faceplate is a blue hexagon icon, which indicates the shelf slot where the card can be physically installed. The 56-port DS-1/E1 card supports two card-protection options, including 1:0 (unprotected) and 1:N, N≤2. The card can be provisioned to operate as either a working or a protection card, reducing spares inventories and their associated cost.

The 56-port DS-1/E1 card supports circuit-level interoperability with the existing Cisco ONS 15454 SONET 14-port DS-1 and SDH 42-port E1 cards. The system supports in-service upgrades from the 14-port DS-1 card, with compatible shelf configurations, using the card upgrade wizard. This allows the user to increase the number of interfaces supported on a shelf assembly or reduce the number of shelf slots required to terminate a given quantity of DS-1 interfaces.

To aid with system troubleshooting and fault isolation, the 56-port DS-1/E1 card supports near-end and far-end performance-monitoring capabilities at the SONET, DS-1, and E1 levels. Loopback support, including near-end and far-end facility (line) and terminal configurations along with far-end activation code (FEAC) support, further simplifies fault-isolation procedures. The card provides three faceplate-mounted status indicators: a red FAIL LED for hardware-level problems; dual color, green/yellow ACTIVE/STANDBY LED to indicate when the card is being used as the active card or a protection card, and a yellow SIGNAL FAIL LED for problems being received on incoming ports. The condition of the card's individual interface ports can be queried using the shelf's liquid crystal display (LCD) panel as well as the browser-based Cisco Transport Controller craft interface. The LEDs will be exercised during a user requested lamp test operation.

Applications

The 56-Port DS-1/E-1 card enables a number of service provider applications including the aggregation of DS-1 services to the central office and E-1 terminations of international traffic.

DS-1 Aggregation

The Cisco ONS 15454 MSPP, using both low-density and high-density DS-1 cards, supports service provider hub applications requiring the aggregation of large quantities of DS-1 services, and transports them to a large central office for hand-off to core-network switches, voice switches, add/drop multiplexers (ADMs), routers, digital cross-connect systems (DCSs), or other networking equipment (Figure 2).

E-1 Termination of International Traffic

The 56-port DS-1/E-1 card enables the termination of internationally sourced E1 service traffic on the Cisco ONS 15454 SONET Multiservice Provisioning Platform (MSPP). The Cisco ONS 15454 SONET MSPP supports optical interfaces that are provisionable for SDH termination, simplifying the E-1 interconnections to the SDH transport equipment (Figure 3).

Key Features and Benefits

Table 1 outlines some of the key features and benefits of the 56-port DS-1/E1 card.

Table 1. Features and Benefits


Feature	Benefits
Provisionable port retiming	Transmit ports can be retimed by the node clock or through-timed from the received client interface signal.
Multiprotocol support	Allows a single card type to support either DS-1 or E1 signals (not at the same time) reducing the number of card variations in spares inventory and the associated cost.
Selectable node timing source	DS-1 and E1 ports can be selected as an input timing source for the network element, providing another option for network timing.
Multiple DS-1 mapping options	Ports can be provisioned for asynchronous or byte-synchronous mapping to VT-1.5s to support the various requirements of terminal equipment.
Support for facility data-link performance monitoring statistics	Capable of receiving status messages from remote equipment supporting FDL per T1.403 and AT&T specifications.
Provisionable J0 section, J1 STS-1 path, and J2 VT path trace support	Enhances network maintenance and troubleshooting activities.
User-defined automatic in-service (AINS) of ports	Allows service port and path to be created awaiting valid signal without creating invalid system alarms.

The 56-port DS-1/E1 card significantly reduces the number of systems required and their associated footprint, power, and cabling to terminate the DS-1 services. The card also helps reduce the number of service cards, opening up shelf slots for other services. Figure 4 depicts a Cisco ONS 15454 OC-12-based network element delivering 112 DS-1 service ports, using the 14-port DS-1 card. Figure 5 depicts the additional services and capabilities that can be delivered over the same footprint by using the 56-port DS-1/E1 card.
