Extended Super Frame (ESF)

Techopedia Explains Extended Super Frame (ESF)

As opposed to the earlier bit-robbing framing methods, ESF is able to maintain 64 Kbps channels and uses an overhead of only 8 Kbps out of each 1.544 Mbps of user data. Out of 8 Kbps overhead, 4 Kbps is used for facility data link, 2 Kbps for framing, and 2 Kbps for CRC.

In ESF, the 193-bit location is redefined to serve mainly three objectives:
  • Maintenance communications
  • Error detection
  • Frame synchronization
Inside an ESF super frame, super frame errors d link, there super frame errors d link 24 bits available to carry out these functions, super frame errors d link. Out of these, synchronization is carried out by using six bits, super frame errors d link, error detection is performed by using another six bits, and the remaining 12 bits are used for maintenance communications.

In D4 framing, 12 bits are used for every super frame to carry out synchronization, whereas in ESF framing, only six bits are used for every super frame to carry out synchronization. D4 framing does not include any link-level error checking, super frame errors d link, whereas the ESF framing implements a six-bit cyclic redundancy check (CRC) pattern to make sure that the frame received has no bit errors.

In addition, super frame errors d link, the 12 bits assigned for maintenance communications provide the maintenance communications channel with a 4,000 bps capacity. This allows the network control center operators to examine remote devices for information regarding the link performance. ESF makes use of the "robbed bits" to execute in-band signaling. ESF uses four frames for each super frame super frame errors d link carry out this kind of signaling.

5.0 out of 5 starsA good basic DSL modem, with no eye-candy features.

Reviewed in the United States on September 22, 2017

Verified Purchase

A good basic DSL modem, with no eye-candy features, etc. Yea! All text user interface! No super frame errors d link graphics (eg, super frame errors d link. GIF/PNG/JPG) within the administration linq to sql association error interface, super frame errors d link. A little difficult at first to setup, as I always enter the incorrect password using the initial "quick setup" option. super frame errors d link However, I further note below the three most important menu items you'll need to know after initially setting up this modem, including changing the ISP login password, and the menus for monitoring for service issues.

My modem log states this modem model having a Broadcom BCM96345 chip, for which Broadcom chips are supposedly strongly preferred for DSL modems. This modem states "Made in China", super frame errors d link, with D-Link's headquarters is in Taiwan. Regardless, super frame errors d link, this is the most recent DSL modem without wireless features available on the market, aside from the older TP-Link DSL non-wirelessmodem. Also, the manual includes GPL/LGPL disclosures. (eg. Yea! Linux & Open Source!)

Purchased this as a replacement for my apparently shorted TP-LINK TD-8816 DSL modem. The TP-Link worked great for 2-3 years, until just after configuration error 0162 windows xp telephone repair man apparently checked the system. Shrugs, super frame errors d link, so I just bought another non-WindStream modem!

This is a good basic modem without any wireless features or eye-candy user interfaces. Very similar to the TP-LINK TD-8816 DSL modem, except there are no GIF/JPEG images within the web browser administration interface for which created problems when printing. This modem also offers telnet/ssh interfacing.

NOTE: The three most important menus within the modem's web administration interface are the following menus;

1) "Device Info" > WAN: Tells you if you are connected to your Internet service provider's network. For example, shows your issued IP address.

2) "Device Info" > Statistics > WAN: Shows your SNR Margin dB, Attenuation dB, speed rates and errors/corrections, super frame errors d link. In other words, line integrity problems. Also includes the previous menu's info.

3) "Advanced Setup" > WAN > Edit to edit your user name and password, super frame errors d link, along with augmenting any other DSL settings for logging into your Internet service provider, super frame errors d link. (eg. UBER, QOS, PPPoA or PPPoE, super frame errors d link, LLC, login password, redial/retry method, MTU .)

Additionally, you may want to turn on logging within Management > System Log, as by default, super frame errors d link, logging is turned-off for some odd reason. Logging is very minimal with the default settings, likely providing some very informative information when trouble-shooting.

If this is your only router/device between your computer and your telephone line (eg. no router), than this device also provides firewall and NAT features, super frame errors d link. If you have a more recently dedicated wireless router or other router, than those dedicated routers may function better than this modem's routing/firewall/NAT (etc) functions as the dedicated hardware tends to perform better than hardware with add-on features.

The other great thing about these cheap modems, if the telephone repair person gets mad at your and decided to short your telephone wiring with 48V shorting any hardware connected to the line, than this $50 modem will likely short-out first and save the remainder of your network system (eg, super frame errors d link. telephones, wireless routers. .) from the excessive voltage. Making this a $50 repair/replace scenario rather than a $150+ for replacing all-in-one DSL modem wireless routers!

ESF comprises 24 individual frames grouped together to form one ESF frame, super frame errors d link. These frames comprise and perform the following functions:

• ESF frame sync bit pattern is reduced to six bits 001011 at the head of frames 4, 8, 12, 16, 20, and 24.

• Robbed bit signaling is extended to frames 18 ("C" bits) and 24 ("D" bits) in addition to frames 6 and 12, as in SF.

• Six bits centos yum loaded plugins error the head of frames 2, 6, 10, 14, 18, and 22 are used as a cyclic redundancy check code (CRC-6) for detection of errors.

• Twelve bits in the odd-numbered frames form a synchronous 4 Kbps data link (DL) channel. This DL channel is used for such functions as the following:

- Protection switching

- Alarm transmission

- Loopback commands

- Received line performance reports (ESFMUs)

- Supervisory or switching command facility

- Network control configurations

ESF framing offers significant advantages over D4 framing, including the following:

• Sixteen possible ABCD signaling states

• False alarm protection if CRC-6 code is checked before certifying frame sync

• Non-intrusive network-monitoring capability

• Data link bits available for network control purposes

The non-intrusive monitoring is performed with a device called an extended superframe monitoring unit (ESFMU). ESFMUs are provisioned by the network service provider on the path of the T1 link across the backbone and are usually placed close to the customers access to the network on each side of the link.

Figure 13-8 illustrates the use of ESFMUs within a network service providers network.
