Release Notes for Cisco ONS 15600 Release 8.0

OL-10906-01

New Features and Functionality

Customer Access Panel

The Customer Access Panel (CAP or CAP2) is located in the middle on the rear of the shelf. The CAP

and CAP2 provide an alarm pin field, timing, and LAN connections. The CAP or CAP2 plugs into the

backplane using 2mm Hard Metric connectors with 752 pins and is held in place with one large captive

bolt and multiple screws.

The CAP2 has the additional capability of providing provisionable power monitoring.

Note The ONS 15600 supports only T1 (100 ohm) building integrated timing supply (BITS).

The ONS 15600 CAP and CAP2 provide the following features:

• BITS T1 (100 ohm) interfaces via wire-wrap pins.

• Two Ethernet interfaces via RJ-45 connectors with internal transformer isolation.

• An EIA/TIA-232 craft interface via DB-9 connectors. This interface is surge-protected and provides

• EMI filtering. Two interfaces are provided for redundancy.

• Four audio alarm interfaces via a DB-15 connector that is surge-protected and EMI-filtered. The

audio alarm indication is provided by the Timing and Shelf Controller (TSC) card and this interface

can receive a signal to disable the audio alarm.

• Four visual alarm interfaces via a DB-15 connector that is surge-protected and EMI-filtered. The

visual alarm indication is provided by the TSC card and the signal is connected to the PDU where

LEDs indicate the alarm status and severity.

• Environmental (external) alarms and controls (16 inputs and 16 outputs) via wire-wrap pins. The

interface is surge-protected and provides isolation by using an opto-isolator for alarm inputs and

relays for alarm outputs. By connecting to different wire-wrap pins on the CAP/CAP2, the alarm

outputs can be configured for either normally open (NO) or normally closed (NC) operation. Alarms

are initiated by shorting these contacts. The alarm input interface provides a pair of positive and

negative wire-wrap pins.

The isolation and termination meet the intra-building lightning surge specification in Telcordia

GR-1089. The CAP and CAP2 have –48 VDC monitoring with an I2C interface and nonvolatile memory

to store the CAP/CAP2 revision information.

If the CAP/CAP2 fails, the node raises an EQPT alarm. You can replace the CAP/CAP2 on an in-service

node without affecting traffic. To replace a CAP, refer to the Cisco ONS 15600 Procedure Guide. Always

replace the CAP during a maintenance window.

New Software Features

SFP Management Completion

Supported services (rates, wavelengths, formats, reach, and so on) are encoded in the EEPROMs of SFPs

and XFPs following industry standards. PPMs (SFPs or XFPs) that do not follow this standard cannot

be read by the platform and are referred to as Unrecognized PPMs.

PPMs that are inserted into a card may be checked for the validity of an MD5 security code. PPMs failing

this test are referred to as non-Cisco PPMs. PPMs passing this test as referred to in this document as

Cisco PPMs.
