Common Control Card Reset
TL1 tunnel specifications and general capabilities include:
Each tunnel generally supports between six to eight ENEs, depending on the number of tunnels at
the ENE.
Each CTC session can support up to 32 tunnels.
The TL1 tunnel database is stored locally in the CTC Preferences file.
Automatic tunnel reconnection when the tunnel goes down.
Each ONS NE can support at least 16 concurrent tunnels.
4.8 Common Control Card Reset
You can reset the common control card for the ONS 15310-MA SDH (the 15310E-CTX-K9 card) by
using the hard-reset or soft-reset commands in CTC. A soft reset reboots the 15310E-CTX-K9 card and
reloads the operating system and the application software. A hard reset temporarily removes power from
the 15310E-CTX-K9 card and clears all buffer memory. Before you hard-reset a card, put the card in
standby mode by completing a soft-reset.
From the node view, select a card and right-click to open a menu with the hard-reset and soft-reset
commands. Soft resets do not impact traffic, but hard resets are service affecting. A card must be in the
Out-of-Service and Management, Maintenance (locked-enabled,maintenance) service state before you
can perform a hard reset.
4.9 Traffic Card Reset
You can reset the CE-100T-8, ML-100T-8, E1_21_E3_DS3_3, and E1_63_E3_DS3_3 cards by using the
hard-reset or soft-reset commands in CTC. A soft reset reboots the card and reloads the operating system
and the application software. A hard reset temporarily removes power from the card and clears all buffer
memory.
Potential to breach DCN
from DCC using IP.
Possible Not possible A potential exists to breach a DCN from a DCC using IP. This
potential does not exist for TL1 tunnels.
IP route management Expensive Automatic For static IP-over-CLNS tunnels, route changes require manual
provisioning at network routers, GNEs, and ENEs. For TL1
tunnels, route changes are automatic.
Flow control Weak Strong TL1 tunnels provide the best flow control.

Tunnel lifecycle Fixed CTC session TL1 tunnels are terminated when the CTC session ends. Static
IP-over-CLNS tunnels exist until they are deleted in CTC.
