ME4600 ONT Series Overview
The CISCO ME4600 ONT RGW equipment runs the CISCO ME4600 ONT-OS software beginning with the
Release 3.0.0.This document provides information about the ME4600 ONT-OS software release starting
from ONT-OS 3.0.0 release.
CISCO ME 4600 ONT Series Overview
The Cisco ME 4600 ONT Series equipment is an Optical Terminal Equipment (ONT) equipment for Passive
Optical Networks (PON) termination in a FTTH (Fiber-To-The-Home) service delivery architecture. Cisco
ME4600 ONT Series equipment communicates with the OLT (Optical Line Terminal) for the PON side and
with the customer’s premises for the client side. This equipment supports triple-play services - high speed
internet (HSI), voice (VoIP), video (IPTV and RF Overlay) and WPS (Wi-Fi Protected Setup). The use of the
GPON fiber access technology does allow a significant service delivery increase when compared with
traditional xDSL technologies.
Cisco ME 4600 ONT Series equipment technology is based on GEM (GPON Encapsulation Method), and
complies with ITU-T G.984.x. recommendation as like as G.984.4 (OMCI) ensuring interoperability with
major GPON OLT vendors (BBF.247).
These base functionalities, together with the support for bit rates of up to 2.5 Gbps (downstream) and 1.24
Gbps (upstream), an optical network splitting ratio of up to 1:64 in a single fiber and a distance range of up
to 60 km, make the GPON technology and the Cisco ME 4600 ONT Series equipment the most efficient
option for passive optical network topologies, when integrated service delivery is an issue.
Together with multi-vendor OLT interoperability (BBF.247 certified), other differentiated features of the
Cisco ME 4600 ONT Series equipment are the embedded RF Video Overlay as well as the chance to have
several TV channel packs by means of using remote managed analog RF video overlay filters. The use of an
embedded optical reflective component also increases probing resolution in case of FTTH probing.
As opposed to the point-to-point architecture, in which there is one physical port per client in the Central
Office, in GPON point-to-multipoint architecture there is only a single laser and photo-detector in the Central
Office (CO) to serve up to 64 CPEs. All the Optical Distribution Network is built by means of passive
equipment modules with a long live MTBF standards and very low OPEX.

Open Issues – CISCO ME4600 ONT-OS 3.2.2
This document section details the unexpected behavior that might be seen with the CISCO ME4600 ONT with ONT-OS
Release 3.2.2
• CSC ONTOS-ME4600-4184
Symptoms: [VoIP] - Supplementary Services - Call Forwarding on Busy Subscriber
Conditions: The “Call Forwarding on Busy Subscriber” supplementary service is not working.
Workaround: There is no workaround
• CSC ONTOS-ME4600-4182
Symptoms: [VoIP] - Call Hold - Ring after on hook
Conditions: After a call is disconnected on a local phone while a second call on hold, the phone will ring
again associated to the call on hold. If the call was originated locally it will not show the phone number of the
other party.
Workaround: There is no workaround
• CSC ONTOS-ME4600-4181
Symptoms: [VoIP] - SIP server Fallback - New calls
Conditions: It becomes impossible to perform new calls when attempting to register a SIP account on the
primary SIP outbound proxy, in a fallback scenario, when the account has previously been successfully
registered on the secondary SIP outbound proxy server.During this period, although the phones connected to
the FXS interfaces signalise any new call coming from the secondary server, the user is unable to accept new
calls.
Workaround: There is no workaround
• CSC ONTOS-ME4600-4180
Symptoms: [VoIP] - Secondary Proxy Server - Fallback
Conditions: Irregular SIP registration renewal occurs when using a secondary SIP Proxy server that use
distinct listening ports from the primary SIP server:
1. Immediately before sending the SIP Register message for the primary server it sends a message to the
secondary which registers the account successfully.
2. As the primary is unavailable sends back to the secondary server when the register retry timeout is reached.
3. In secondary server now registers the account twice in a row that added to the first gives a total of 3 SIP
records in a short time.
When both servers are unavailable, the time between retries doubles after the first cycle of registration
attempt.
When only the primary server is available, the RGW registers the account twice on the primary outbound
proxy.
Workaround: There is no workaround
• CSC ONTOS-ME4600-4179
Symptoms: [VoIP] Outbound Proxy Server Address needs to be configured
Conditions:
▄ Release Notes for the Cisco ME4600 ONT-OS 3.2.2 Series
12
▀
The options available on the RGW WebUI indicate that it is possible to configure the VoIP service without
the Outbound Proxy Server Address.
But when this option is used the RGW keeps the outbound proxy server option keeps enabled and
reconfigures the Address and port parameters to 0.0.0.0/0.
After a START/STOP/STOP actions the RGW WebUI is no longer available, rebooting and after a few
minutes. reboots it self.
Workaround: Always configure the outbound proxy server address.
• CSC ONTOS-ME4600-4176
Symptoms: [VoIP] Reserved Characters on SIP server URI
Conditions:
The RGW allows the use of reserved characters on the SIP server URI Registrar,Proxy,Outbond Proxy, Sec
Outbond Proxy).
This should not be possible.
After doing a STOP/START on the SIP Client it's no longer possible to do a STOP action on the SIP client.
Also the WebUI and telnet interface is no longer available. The device appears as absent on the OLT after a
while.
Workaround: There is no workaround
• CSC ONTOS-ME4600-4145
Symptoms: [TR-104] Disable interface wan with VoIP account registered
Conditions:
When disabling an interface used by de VoIP service, the associated VoIP accounts are not unregistered first,
being the device LEDs for VoIP turned ON even when the account is presented as unregistered at status
page.When the VoIP service is not assigned to a specific interface if the WAN interface required for
accessing the SIP servers is disabled, the accounts remain as being registered according to the data presented
in the webGUI status page, on the LEDs indication, and on the data obtained through TR069. This status is
incorrect, since the user is unable to establishVoIP calls.
Workaround: There is no workaround
• CSC ONTOS-ME4600-3927
Symptoms: [IPoE IPv6] - IPv6 only
Conditions: When a IPoE IPv6 only interface is created the ONT only solicits a IPv6 prefix after a reboot.
Workaround: There is no workaround
• CSC ONTOS-ME4600-3926
Symptoms: [IPv6] - DISABLE/ENABLE
Conditions: If a IPoE IPv6 only or a PPPoE IPv6 enabled interface is disabled/enabled the ONT does not
solicit a IPv6 prefix.
Workaround: There is no workaround
• CSC ONTOS-ME4600-3925
Symptoms: [IPoE IPv6] - Prefix Release
Conditions: The ONT does not release its assigned IPv6 prefix when the interface is removed or disabled.
Workaround: There is no workaround
Release Notes for the Cisco ME4600 ONT-OS 3.2.2 Series ▄

▀
• CSC ONTOS-ME4600-3924
Symptoms: [PPPoE IPv6] - Prefix release
Conditions:
The ONT does not release the IPv6 prefix of a PPPoE interface when the interface is disabled/removed or
when it is gracefully restarted.
Workaround: There is no workaround
• CSC ONTOS-ME4600-3923
Symptoms: [PPPoE IPv6] - Firewall
Conditions: The ONT does not activate the firewall for IPv6 on PPPoE interface. On the WebUI the firewall
status is enabled.
Workaround: There is no workaround
• CSC ONTOS-ME4600-3921
Symptoms: [IPv4] WAN IPoE - DHCPv4 NAK
Conditions:
When the ONT receives a DHCPv4 NAK message it is expected to restart the DHCP IP address allocation
with a DHCPv4 Discover message. Currently the ONT acts as if it ignores the DHCPv4 NAK message.
Workaround: There is no workaround
• CSC ONTOS-ME4600-3918
Symptoms: [IPv6] - PPPoE Restart
Conditions:
When a Dual Stack PPPoE session is restarted the ONT does not initiate the DHCPv6-PD process.
This restart can be a local reset on the PPPoE credentials, remote SPV of the PPPoE credentials via HDM or
a simple local PPPoE interface disable/enable.
Workaround: ONT reboot
• CSC ONTOS-ME4600-3906
Symptoms: [Multicast] Multicast MACs are discarded in WAN bridge interface
Conditions:
Traffic with Multicast MAC address (01:00:5E:xx:xx:xx) is discarded by the ONT when transmitting the
traffic through a service configured to the VeIP.
This problem occurs with only 1 unicast service configured on the OLT (stacked or unstacked), being the
traffic transmitted through this unicast service.
The OLT forwards the traffic to the ONT (visible by consulting the OLT counters) but is discarded by the
ONT when the MAC is started by 01:00:5E.
This behavior is not detected on the SFU, being this type of traffic accepted.

• CSC ONTOS-ME4600-2946
Symptoms: [QoS] Performance - Full Queues - High overflow
Conditions: When misbehaved data flow with a low priority starts occupying a considerable bandwidth the
QoS system stops working.
Workaround: There is no workaround
• CSC ONTOS-ME4600-2945
Symptoms: [QoS] Performance - Full Queues - Mild overflow
Conditions: When all queues are occupied there are some moments when the QoS mechanism does not work
as expected.
Some of the events detected are the following:

Data flow is completely cut from transmission permanently.

Data flow is partially cut from transmission permanently.
Workaround: There is no workaround
• CSC ONTOS-ME4600-2943
Symptoms: [QoS] - Queues Priority
Conditions: On the RGW WebGui it's referred "(lower value, higher priority)". During the Tests it was
verified that it's the opposite: Higher value, higher priority.
Workaround: There is no workaround
• CSC ONTOS-ME4600-2939
Symptoms: [CLI] PPPoE - Dial on Demand - IPv6
Conditions: When Dial on Demand feature is enabled, the IPv6CP protocol is abnormally terminated by the
RGW on the PPPoE session establishment after an initial phase where it has followed the regular IPv6CP
negotiation. This aborts the IPv6 connectivity procedure.
Workaround: There is no workaround
• CSC ONTOS-ME4600-2936
Symptoms: [CLI] - IPv6 Prefix Information
Conditions: On the CLI interface it's not possible to obtain any details regarding the DHCPv6 IPv6
Delegated Prefix.

• CSC ONTOS-ME4600-2927
Symptoms: [VoIP] SIP Authentication Header
Conditions: In the first SIP REGISTER message the RGW SIP client sends the Authentication Field without
any values on the nonce and response parameters.
This is not a standard behavior.
Usually on the first SIP register message no authentication header is included. Only after the server answers
with the "401 Unauthorized" SIP message containing the type of authentication, nonce, realm, algorithm the
client sends a new SIP REGISTER message with the Authentication message with the appropriate parameters
and values.
Workaround: There is no workaround
• CSC ONTOS-ME4600-2923
Symptoms: [VoIP] Secondary Proxy Server - Fallback - Active call Media Session
Conditions: During the proxy server switch the active call media session is lost.
The RGW stats answering with ICMP Destination unreachable (Port Unreachable) messages to the RTP
packets sent by the media server. The RGW does not notify the telephone that the call is no longer active.
Workaround: There is no workaround
• CSC ONTOS-ME4600-2907
Symptoms: [VoIP] - VIA Header
Conditions: The VIA header sent by the RGW on its SIP messages does not contain the source port used.
If by some reason the RGW SIP client is unable to use the source port 5060 the RGW will not be able to
communicate with the SIP server as the messages sent by the Cisco VoIP server are sent to the SIP default
port 5060 regardless of the port used on the IP/UDP packet.
Workaround: There is no workaround
• CSC ONTOS-ME4600-2902
Symptoms: Loss of communication with the ONT after associate bridge 4 to ETH4
