Chapter 3, Electrical Cards and Cable

This chapter describes Cisco ONS 15454 electrical card features and functions. For installation and card turn-up procedures, refer to the Cisco ONS 15454 Procedure Guide. For information on the electrical interface assemblies (EIAs), see the "Electrical Interface Assemblies" section on page 1-14.

3.1 Electrical Card Warnings

Warning Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.

Note Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly. The cards are then installed into slots displaying the same symbols. See the "Card Slot Requirements" section on page 1-37 for a list of slots and symbols.

3.2 EC1-12 Card

The EC1-12 card provides 12 Telcordia-compliant, GR-253 STS-1 electrical ports per card. Each port operates at 51.840 Mbps over a single 75 ohm 728A or equivalent coaxial span.

STS path selection for UNEQ-P, AIS-P, and bit error rate (BER) thresholds is done on the SONET ring interfaces (optical cards) in conjunction with the STS cross-connect. The EC1-12 terminates but does not select the 12 working STS-1 signals from the backplane. The EC1-12 maps each of the 12 received EC1 signals into 12 STS-1s with visibility into the SONET path overhead.

An EC1-12 card can be 1:1 protected with another EC1-12 card but cannot protect more than one EC1-12 card. You must install the EC1-12 in an even-numbered slot to serve as a working card and in an odd-numbered slot to serve as a protect card.

3.2.1 EC1-12 Slots and Connectors

You can install the EC1-12 card in any multispeed or high-speed card slot on the ONS 15454. Each EC1-12 interface features DSX-level (digital signal cross-connect frame) outputs supporting distances up to 450 feet depending on facility conditions.

3.2.2 EC1-12 Faceplate and Block Diagram

3.2.3 EC1-12 Hosted by XC, XCVT, or XC10G

All 12 STS-1 payloads from an EC1-12 card are carried to the XC, XCVT, or XC10G card where the payload is further aggregated for efficient transport. XC and XCVT cards can host a maximum of 288 bidirectional STS-1s. XC10G can host up to 1152 bidirectional STS-1s.

3.2.4 EC1-12 Card-Level Indicators

Table 3-1 EC1-12 Card-Level Indicators
Card-Level Indicators	Description
Red FAIL LED	The red FAIL LED signifies that the EC1-12 card's processor is not ready. Replace the unit if the FAIL LED persists.
Green ACT LED	The green ACT LED indicates that the EC1-12 card is operational and ready to carry traffic.
Amber SF LED	The amber SF LED indicates a signal failure or condition such as loss of signal (LOS), loss of frame (LOF) or high bit error rate (BER) on one or more of the card's ports.

3.2.5 EC1-12 Port-Level Indicators

You can obtain the status of the EC1-12 card ports using the LCD screen on the ONS 15454 fan-tray. Use the LCD to view the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot.

3.3 DS1-14 and DS1N-14 Cards

The ONS 15454 DS1-14 card provides 14 Telcordia-compliant, GR-499 DS-1 ports. Each port operates at 1.544 Mbps over a 100 ohm twisted-pair copper cable. The DS1-14 card can function as a working or protect card in 1:1 protection schemes and as a working card in 1:N protection schemes.

The DS1-14 card supports 1:1 protection. The DS1-14 can be a working card in a 1:N protection scheme with the proper backplane EIA and wire-wrap or AMP Champ connectors. You can also provision the DS1-14 to monitor for line and frame errors in both directions.

You can group and map DS1-14 card traffic in STS-1 increments to any other card in an ONS 15454 except DS-3 cards. Each DS-1 is asynchronously mapped into a SONET VT1.5 payload and the card carries a DS-1 payload intact in a VT1.5. For performance monitoring purposes, you can gather bidirectional DS-1 frame-level information (loss of frame, parity errors, cyclic redundancy check [CRC] errors, etc.).

3.3.1 DS1N-14 Features and Functions

The DS1N-14 card supports the same features as the DS1-14 card in addition to enhanced protection schemes. The DS1N-14 is capable of 1:N (N<5) protection with the proper backplane EIA and wire-wrap or AMP Champ connectors. The DS1N-14 card can function as a working or protect card in 1:1 or 1:N protection schemes.

3.3.2 DS1-14 and DS1N-14 Slots and Connectors

You can install the DS1-14 card in any multispeed or high-speed card slot on the ONS 15454. Each DS1-14 port has DSX-level (digital signal cross-connect frame) outputs supporting distances up to 655 feet.

If you use the DS1N-14 as a standard DS-1 card in a 1:1 protection group, you can install the DS1N-14 card in any multispeed or high-speed card slot on the ONS 15454. If you use the card's 1:N functionality, you must install a DS1N-14 card in Slots 3 and 15. Each DS1N-14 port features DSX-level outputs supporting distances up to 655 feet depending on facility conditions.

3.5 DS3-12E and DS3N-12E Cards

The ONS 15454 DS3-12E card provides 12 Telcordia-compliant ports per card. Each port operates at 44.736 Mbps over a single 75 ohm 728A or equivalent coaxial span. The DS3-12E card provides enhanced performance monitoring functions. The DS3-12E can detect several different errored logic bits within a DS-3 frame. This function allows the ONS 15454 to identify a degrading DS-3 facility caused by upstream electronics (DS-3 Framer). In addition, DS3 frame format auto detection and J1 path trace are supported. By monitoring additional overhead in the DS-3 frame, subtle network degradations can be detected.

The DS3-12E supports a 1:1 protection scheme, meaning it can operate as the protect card for one other DS3-12E card.

3.5.1 DS3N-12E Features and Functions

The DS3N-12E can operate as the protect card in a 1:N (N<5) DS-3 protection group. It has additional circuitry not present on the basic DS3-12E card that allows it to protect up to five working DS3-12E cards. The basic DS3-12E card can only function as the protect card for one other DS3-12E card.

3.5.2 DS3-12E and DS3N-12E Slots and Connectors
